Zauli Title: The electronic spectrum of pyrrole in the vapour and crystal Journal/Source: Molecular Physics, 31 (2), 479-489, (1976); DOI:10.1080/00268977600100361 Data: table, diagram Energy/Wavelength range: < 39000 cm-1 (< 256 nm) Resolution: Temperature: Temperature dependence: Pressure/Concentration: Phase: vapor, crystal pH: Comments: The vapour spectrum of pyrrole was investigated below 39000 cm-1. Four Rydberg-like series were observed with a vibrational pattern. There is a weak system near 46000 cm-1 and very weak absorption in the range 40000-44000 cm-1. The crystal spectrum in polarized light was measured in the range 45000-55000 cm-1. Author to whom correspondence should be addressed: (e-mail address):
