Induced Circular Dichroism of beta-Cyclodextrin Complexes with Azanaphthalenes-Polarization Directions of the ?* <- ? Transitions in Azanaphthalenes The induced circular dichroism (ICD) spectra of cyclodextrin (beta-CDx) complexes with mono-, di-, and triazanaphthalenes were measured in the wavelength region 200-400 nm.The polarization analysis and spectral assignements of these azanaphthalenes were made from the comparison of the theoretical results calculated by using the CNDO/C-SI approximation with the observed ICD spectra.The polarization directions of the first ?* <- ? transition in azanaphthalenes are closely related to the position of aza nitrogen and can be determined by the coefficients of the configurations in corresponding lowest ?* <- ? states.From the observation of the ICD bands with mixed signs, the presence of the "forbidden" character is strongly suggested in the second absorption bands of isoquinoline, cinnoline, and quinazoline.In each case of azanaphthalenes, the observation of positive ICD bands in the third absorption band indicated the predominance of the long-axis-polarized electronic transition. We¡¯ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, the role of 253-52-1, and how the biochemistry of the body works.Reference of 253-52-1
