Vibrational spectra of [1H4]pyrazine and [2H4]pyrazine
Abstract
Infrared and Raman spectra of [1H4]pyrazine and [2H4]pyrazine have been reinvestigated and a general assignment of all the observed bands is proposed which modifies some previous assignments of fundamental vibrations. The present assignment satisfies the isotopic product rule for i.r.- and Raman-active fundamentals. On this basis thermodynamic functions have been computed.
