Box 23-166, Taipei 107, Taiwan, Republic of China.; National Taiwan University, Taipei 107, Republic of China.By laser-induced fluorescence (LIF), we previously detected 22 UV bands due to transitions from vibrationally excited states of to Five new bands of parallel-type transitions are rotationally analyzed. The LIF spectrum of the 35929, 36658 and bands were obtained after photolysis at 193 nm of a supersonic beam of argon seeded with acetylene; two other bands at 38360 and , assigned as and , were recorded after photolysis at 193 nm of a mixture of acetylene and at high pressure. States S and V represent K=0 and 2 stacks of a single vibrational level T, located at , of . Gating at the fluorescence lifetime enables us to separate weak bands of CCH from . Methods of obtaining vibrationally cooled CCH will be discussed

Phys. 103, 5919(1995).Author Institution: Institute of Atomic and Molecular Sciences; Department of ChemistryIn the range, eight new bands of CCH transition were observed by laser-induced fluorescence. By rotational analysis, they have been assigned as transitions from low vibronic levels, and ) of CCH to two vibrational levels (T, T+1221) of the state. Most of these bands were difficult to be detected if a acetylene/argon or helium gas mixture was photolyzed to produce CCH. Due to population transfer, via collisions with , from higher vibronic levels of CCH which were predominantly produced in the 193.3 nm photolysis of acetylene, spectral intensities of these bands were thus enhanced. Spectroscopic parameters of and were obtained for the first time. Spectral lines of transition recorded in a supersonic beam were also included in a simultaneous fit, spectroscopic parameters of were accordingly better determined in this work than our previous The vibronic energy levels of CCH up to were approximated as three anharmonic oscillators, where is 401 cm. The anharmonicities and 911#### obtained from the fit will be given
NEGATIVE ANHARMONICITIES OF THE BENDING VIBRATION OF CCH AND THE TRANS-BENDING VIBRATION OF THE ACETYLENE CATION
No full text1. E. Hirota, Chem. Rev. 92, 141 (1992). 2. Y.-C. Hsu, J. J.-M. Lin, D. Papoušek, and J. -J. Tsai, J. Chem. Phys. 98, 6690 (1993).Author Institution: Academia Sinica, P. O. Box 23-166, Taipei, 107, Taiwan Republic of China; National Taiwan University, Taipei, 107, Republic of China.The levels of the bending vibration of were determined by UV laser-induced fluorescence of the products of photolysis of acetylene at 193 nm. Large negative anharmonicity was found in the lowest five levels of the bending vibration. As the number of bending quanta increases, the anharmonicity decreases considerably. Levels of the trans-bending motion of the acetylene cation , isoelectronic with and its deuterated isotopomer have been determined by 1 + 1 PFI-ZEKE spectroscopy via a single rovibronic level of as an intermediate. Spectral analysis shows that negative anharmonicity was also present in the latter case. Large negative anharmonicity of CCH is attributed to vibronic between and as well as vibration-rotational interaction among the vibrational levels of the . The potential-energy curve of the bending vibration of CCH and that of the trans-bending vibration of calculated by an ab initio method will be presented to show that negative anharmonicities of these molecules may be due to the flatness of the (zero-order) potential-energy curves. The Renner-Teller effect of the trans-bending vibration of the acetylene cation will be discussed
