Abstract
The absorption spectrum of pyridine at 3000–2500A has been studied in the first order of a 3‐m grating spectrograph. The band system represents an electronic transition A1→B1 (using symmetry C2v for pyridine). Several progressions of totally symmetric vibrations are observed. The band 34769 cm−1 is taken as 0,0 band. Besides carbon ring vibrations the occurrence of hydrogen vibrations is established and discussed.Keywords
