Abstract
The rotational structure of (2,0) vibrational band of A(2)Pi (1)-X(2)Sigma (+) transition of CN has been studied by concentration-modulation laser spe ctroscopy using a Ti:sapphire laser. The CN radical was produced in the ac glow discharge of acetonitrile with helium as the carrier gas, All 12 branc hes including four new branches have been observed and measured with an abs olute accuracy of 0.007 cm(-1) in the region 12 450-12 750 cm(-1). Analysis of the spectra has led to improved molecular parameters Of the A(2)Pi (i) (v' = 2) state. (C) 2001 Academic Press.
