Abstract
Solid powders of long methylene chain diamines NH2-(CH2)(n)-NH2 with n = 10, 12, and their newly synthesized copper complexes were studied b y laser visible Raman spectroscopy. In this study, we mainly focus on the intensity variations of both the symmetrical and anti-symmetrical stretching vibrational modes of the CH2 groups situated in the high-fr equency range 2800-3000 cm(-1) and on the skeletal vibrations (C-C bon ding) in the region 1050-1150 cm(-1), which shows an unusual behaviour upon complexation of the diamines with the copper ion.
