✦ Synopsis

Both 6,12-diphenylazuleno[ 1,2-b] azulene and 6,12-dip-bromophenylazuleno [1,2-b] azulene exhibit similar absonztion and MCD spectra. PPP caIcuIations reproduce the observed absorption and MCD spectra. The phenyi andp-bromopheny1 groups are considered to present no obstacle in investigating the spectroscopic behavior of azuIeno [ 1,2-b] azulene.

## Abstract The magnetic circular dichroism and UV. spectra of 2‐methyl‐1, 3‐diazaazulene (**2**) have been measured. The UV. spectrum is interpreted by making use of CNDO/S MO CI calculations. Our assignment of the first and second absorption band coincides with one of the corresponding bands of 1
