Warner, Astrophys, J. 342, L99 (1989).Author Institution: Herzberg Institute of astrophysics, National Research Council; Heyrovsk\'y Institute of Physical Chemistry, Academy of Sciences of the Czech Republic; Department of Physics and Astronomy, Ibaraki UniversityThe ground state rotational spectrum of protonated formaldehyde,

H_{2}COH^{+}

, has been identified and assigned following the infrared detection by Amano and

Warner^{1}

, using a magnetically confined extended negative glow discharge as a production source. The molecular constants have been determined more accurately. These parameters provide the pure rotational transition frequencies which are accurate enough for radio astronomical searches for this ion in interstellar molecular clouds

This paper discusses the credibility issue of correction/enlargement of An English-Japanese Dictionary, second edition , originally compiled and translated by Masakichi Shibata and Takashi Koyasu in 1873(6th year of Meiji), corrected by Tameyuki Amano and enlarged by Choyo Suzuki published in 1886 (19th Year of Meiji). This bilingual dictionary has been undervalued as a mere reprinted version of its first edition which was published in 1885 (18th year of Meiji) by Kobayashi Kamenoshin. If this is true, therefore, the ‘correction/enlargement,’ so written on the title page of the Amano-Suzuki second edition (1886), has no meaning at all. However, the present author incidentally found a unique translation equivalent for ‘giraffe’ in the Amano-Suzuki dictionary (Murahata, 2021). We cannot find the equivalent in any of the English-Japanese dictionaries which have ever been published in Japan since the end of the Edo period. Comparing traslation equivalents for more than 2,600 headwords in the dictionary with those in four closely related dictionaries, this paper seeks for more credible evidence to renounce the underestimation that the Amano and Suzuki dictionary is just a facsimile of the first edition and confirm the reality that the dictioinary is actually a new version preciously and carefully corrected and enlarged, if not drastically, by Amano and Suzuki.departmental bulletin pape

CH_{4}(\sim 4mTorr)

He(\sim 240 m Torr)

technique^{b}

and the zero field transition frequencies were calculated with 1.5 MHz accuracy by Brown and

Evenson^{c}

. From our new direct observation, more accurate transition frequencies were determined with typically

uncertainty. Astrophysically these accurate frequencies will be of great use for probing hydrocarbon chemistry in warmer and denser regions of molecular clouds

) in the THz

region^{b}

. Polyansky and McKellar derived more accurate molecular constants and term values by combining all the available

data^{c}

. However, since the molecule is very light, even such revised molecular constants should be subject to critical tests. The line position of the

1_{10} - 1_{01}

transition was predicted to be 691.705 GHz by using previous IR data. A backward-wave oscillator based submillimeter-wave system was used for the observation of the spectra. The

D_{2}H^{+}

molecules were generated in an extended negative glow discharge in gas mixture of

H_{2}

and

D_{2}

with Ar as buffer gas near liquid nitrogen temperature (77 K). Following numerous efforts, in the range of the expected spectral region, we discovered only one signal at 691.660440 GHz that was highly sensitive to magnetic field that was applied to the discharge to achieve the extended negative glow condition. This absorption line vanished by cutting off

H_{2}

D_{2}

gas, by inducing tiny air leak, or by raising cell temperature. In contrast to

H_{2}D^{+}

, the mixing ratio of

H_{2}/D_{2}

was found to be less sensitive in producing

D_{2}H^{+}

. This behavior was similar to the findings in previous IR spectroscopy at

NRC^{a,d}

. The optimum mixing ratio of gases was found to be

H_{2}/D_{2}/Ar = 4/2/17

mTorr and discharge current was about 8 mA. The observed line width

(FWHM = 1.7 MHz)

was comparable with the Doppler line width of the molecule

(FWHM = 1.9 MHz)

, assuming that the temperature of the cell was 77 K. A set of the improved molecular constants was obtained by combining all available IR data

The Fox and the Grapes

Author: No Author
Publication venue
Publication date: 01/01/2000
Field of study

This is a 28-page large-format pamphlet that needs a plain brown wrapper. It is titled (in English) The fox and the grapes. The title-page has a clear English announcement Adult only. The bulk of the book is then a black-and-white graphic novelette that is indeed graphic! From my quick look I have little sense of how the fable of the fox and the grapes is played out in this intense sexual adventure (or adventures?). I offer one last word of warning. Do some or all Japanese books work from our back to our front? The pages, I notice, are numbered that way, and now I see that what I took for the back cover is an appropriate cover with the same English title and warning as the title-page. Aesop provokes a great deal!Language note: JapaneseKanon: Makoto Sawatori and Mishio Aman

DIFFERENCE FREQUENCY LASER SPECTROSCOPY OF MOLECULAR IONS

Field of study

Address of Nakanaga and Amano: Herzberg Institute of Astrophysics, National Research Council of Canada, Ottawa, Ontario, Canada KIA OR6.Author Institution:A hollow cathode discharge cell has proven to be an excellent source of positive ions. In the past few years, we have attained a significant improvement in sensitivity of the system which enables us to search for weaker lines of more complicated ions. In this talk, we will present our recent results on three symmetric top ions of astrophysical interest,

NH_{3}D^{+}, CH_{3}CNH^{+}

, and

SH^{+}_{3}

, detected in absorption in a modulated discharge through the mixtures of

NH_{3}

and

D_{2}. CH_{3}CN

and

H_{2}

, and

H_{2}S

and

H_{2}

, respectively. This is the first high-resolution spectroscopic detection of

CH_{3}CNH^{+}

and

SH_{3}^{+}

. Both the

\nu_{1}

band of

CH_{3}CNH^{+}(\nu_{0}-3527.288 cm^{-1})

and the

\nu_{3}

band of

SH_{3}^{+}(\nu_{0}=2525.78 cm^{-1})

exhibit a clear sign of perturbations. In

SH^{+}_{3}

, the perturbation is more conspicuous, and an extra band yet to be identified is also obsered. The rotational constants for the ground state have been determined for both

SH^{+}_{3}

and

CH_{3}CNH^{+}

through a least squares fit by using the combination differences. The lines of

SH_{3}^{+}

show no sign of the inversion doubling, and the preliminary molecular constants obtained agree well with ab initio predictions. The rotational transition frequencies have been calculated to assist in future search for these ions in interstellar space.

NH_{3}D^{+}

possesses a permanent dipole moment of about 0.26 D, and it will be possible to detect the rotational transitions in the millimeter and sub-millimeter-wave region in interstellar space and in the laboratory. Our analysis of the

\nu_{4}

fundamental band

(\nu_{0}=3341.0764 cm^{-1})

provides a prediction of the rotational transition frequencies
