The A-X system of the SbO+ molecule

Abstract

The spectrum of the SbO+ molecule has been studied under high resolution for the first time. Analysis of the rotational structure in (1,2) and (1,3) bands leads to the following rotational constants: B'1=0.325 13 cm-1, D'1=2.09*10-7 cm1; B"2=0.359 64 cm-1, B"3=0.357 41 cm-1, B"e=0.365 13 cm-1, a"e=0.002 23 cm-1, D"2=1. 57*10-7 cm-1, D"3=1.47*10 -7 cm-1, r"e=1.8074 AA; nu (1,2)=23 568.12 cm-1, nu (1,3)=22657.79 cm -1.
