However, treating 2-lithiothiophene with quinoline at 20ยฐC by Giiman's methodf6] leads only to 2-(2-thienyl)quinoline (2) (38%), indicating steric hindrance of 4-addition by the peri-hydrogen atom of the quinoline. In the following reactions of the quinoline system with 2-lithiothiophene derivatives

Absorption, fluorescence emission and fluorescence excitation spectra of the g 'A' +% IA' (IT\* + d band system of UFCS in the gas phase at room temperature and at -78ยฐC have been measured.

The emission spectra of the second excited singlet state of [ 181 annukne and of monofluoro [ 181 annulene (m a 3methylpentanc glass at 4 K) are reported. The large ener,7 gap between the fist and second excited singlet states inhibits fast internal cogversion and favours the appearance of S2 + So e
Fluorescence has been observed from the second excited singkt stste of tkiophosgene vapour. The emission is excited mainly by transitions originating in the out-of-plane bending mode of the ground stzte and terminating in the lowest vibrational levekof the-excited state. i '.
