✦ Synopsis

Emission spectra of the CN violet band system (B *Z-X *S) were observed by the eIectron impact on HCN with seberal impact ener@s near me thieshold.

These re-SU& swest tit an optimuy aUowed state corn&t&s to the formation of CN(B) from HCN as a main precursor.

The core-excited negative ion resonances in H,O, first observed by Senche and Schulz, have been identified in both the (O-O) and (1-O) bands of the OH(A\*Z -+ X \*II) emission following near-threshold electron impact. These observations allow limits to be placed on the energy of the predissociating
