High-Resolution infrared spectra of aluminum hydride and gallium hydride produced in a heat pipe cell by the reaction of corresponding metals with hydrogen at high temperature were successfully observed with an FTIR spectrometer. The 88 and 111 transitions for AlH and GaH were measured and the molecular constants were refined by fitting the newly observed and already reported transitions simultaneously. Intensity analyses were carried out to estimate the Herman-Walls effect. The sensitivity of the FTIR is discussed by comparing it with that of infrared diode laser method.
