摘要:

Vibrational analysis of the electronic absorption spectrum of ethylpyrazine observed around 320 nm is carried out. The bands are ascribed to the longest wavelength one of the four possible π* ← n systems. A “vibronic” interaction between the excited state of this system and another excited state of the molecule is observed. A π* ← π system with practically no vibrational structure is also observed and discussed.
