No full textCircular Dichroism Spectra (350-185 nm) of a New Series of 4-Substituted [2.2] Paracyclophanes: a Quantitative Analysis within the De Voe Polarizability Model
No full textThe CD spectra of a new series of 4-substituted [2.2]paracyclophanes 1b- e have been measured down to 185 nm. Polarizability calculations within the DeVoe model satisfactorily reproduce the CD features over all the spectral range. In addition, the analysis of the complete CD spectrum allowed a phenomenological interpretation of the dependence of the sign of [α](D) on the nature of the substituents, at least for X=F, OH, I
The Picard group of the universal moduli stack of principal bundles on pointed smooth curves II
No full textIn this paper, which is a sequel of [14], we investigate, for any reductive group G over an algebraically closed field k, the Picard group of the
universal moduli stack BunG;g;n of G-bundles over n-pointed smooth projective curves of genus g. In particular, we give new functorial presentations of
the Picard group of BunG;g;n, we study the restriction homomorphism onto the
Picard group of the moduli stack of principal G-bundles over a fixed smooth
curve, we determine the Picard group of the rigidification of BunG;g;n by the
center of G as well as the image of the obstruction homomorphism of the associated gerbe. As a consequence, we compute the divisor class group of the moduli space of semistable G-bundles over n-pointed smooth projective curves of
genus g
The Picard group of the universal moduli stack of principal bundles on pointed smooth curves
No full textFor any smooth connected linear algebraic group G over an algebraically closed field k, we describe the Picard group of the universal moduli stack of principal G-bundles over pointed smooth k-projective curves
