Measurement of the transition dipole moment of silane 28SiH4 by diode laser spectroscopy

Abstract A tunable diode laser IR spectrometer which is being used in various molecular spectroscopy experiments is described. Absorption spectra observed in the ( ν 1 , ν 3 ) dyad of silane 28 SiH 4 yield estimates of two parameters of the dipole moment operator responsible for absorbance in this region.
