Abstract
The observation and analysis of 187 lines in the 2–0 band of the A 2Πi ← X 2Σ+ system of the SiN radical are described. The 2–0 band, which lies near 3.3 μm, has been recorded with a tunable difference frequency system and discharge amplitude modulation. The analysis gives improved molecular constants for the ground and first excited states, including the first lambda doubling parameters for the A 2Π state.Keywords
