Abstract

The infrared absorption spectrum of $S i H 4$ has been recorded from $2100 c m −1$ to $2300 c m −1$ at a resolution of $0.017 c m −1$ and deconvoluted $0.006 c m −1$ . Approximately 800 $ν 3$ lines have been assigned and analyzed through J = 18 including the intense $ν 1 – ν 3$ interaction. The constants for $28 S i H 4$ are in good agreement with previous $w o r k . 1$ The $29 S i H 4$ and $30 S i H 4$ results will be presented as well. The Coriolis constant, $ζ 3 z$ for each isotope is in good agreement with force field $c a l c u l a t i o n s . 2$
