概要

• 論文の詳細を見る

• A normal coordinate analysis of the in-plane vibrations of diacetamide and of diacetamide-d taking the trans-trans configuration has been undertaken. The calculated frequencies agree well with the observed frequencies for the crystals in form B. The Urey-Bradley force field has been adopted, and the force constants obtained have been interpreted in terms of the difference in resonance structures between amides and imides. It has been shown that the vibrational modes of the characteristic imide frequencies are closely related to the behavior of the corresponding characteristic bands upon the change in the alkyl frameworks attached to the imide group.
