TL;DR: In this paper, the vibrational wavenumbers of the title compound were computed using the B3LYP/6-31G* basis and compared with the experimental data.
Journal ArticleDOI
Spectroscopic investigations and computational study of 2-[acetyl(4-bromophenyl)carbamoyl]-4-chlorophenyl acetate
C. Yohannan Panicker,Hema Tresa Varghese,K. C. Mariamma,Koshy John,Samuel Mathew,Jarmila Vinšová,Christian Van Alsenoy,Y. Sheena Mary +7 more
TL;DR: In this article, the Fourier transform Raman (FT-Raman) spectra of 2-[acetyl(4-bromophenyl)carbamoyl]-4-chlorophenyl acetate were studied theoretically using the Gaussian03 set of quantum chemistry codes, and the normal modes were assigned by potential energy distribution (PED) calculations.
