Electronic absorption spectrum of 6-chloroindole

Abstract Despite our studies on the π* ←π system in some substituted indoles (E. V. Huded, N. H. Ayachit, M. A. Shashidhar and K. Suryanarayana Rao, Spectrochim. Acta 42A, 1407 (1986) and the references mentioned therein ) the available data are limited. We therefore report and interpret the vapour phase electronic absorption spectrum and infrared spectrum of 6-chloroindole.
