Etude des spectres de vibration des dérivés monosubstitués en position 5 de l'isothiazole

Abstract: The i.r. absorption spectra in different physical states and the Raman spectra in the liquid or solid state of 5-monosubstituted isothiazole derivatives, C3NSH2Y (Y = CH3, CD3, Cl, Br, I) have been analyzed. An assignment of the fundamental modes of vibration of these molecules is given.

“…The bands at 1098 cm-' and near 1 180 cm-' are aromatic in-plane C-H deformation T h e hand at 1284 cm-I arises from the two-substituted ben-zoxazole group. 32,33 The band at 1404 cm-1 that does not appear in WW93 is assigned to the benzoxazole-butadiene chromophore. The band at 1462 cm-* is a characteristic oxazole band,32 assigned by Simonov et to the C-N bond.…”

“…Dans l'hypothkse d'un transfert possible de ce champ de forces, nous avons entrepris un calcul des modes normaux de vibration pour quelques composks de l'isothiazole lnonosilbstituis en position 3, 4 ou 5, C3NSH2Y (U = CI-13, CD3, C1, Br ou I), afin de kirifier ou de priciser les attributions expkrimentales que nous avons proposies antirieurement (2)(3)(4).…”
