New infrared (for gas and liquid phase) and Raman (for liquid) spectrawere measured for the chlorotrimethylgermane to obtain a complete assignment of its fundamental modes. The measurement of the low-temperature infrared spectrum together with the application of Fourier self-deconvolution to the Raman spectra resolves the C–H vibrationalmodes into their components. The Rauhut and Pulay scaled quantum mechanical (SQM) force field methodology and the wavenumber-linear scaling (WLS) method were used to predict the vibrational spectra as a guide to the assignment of the fundamental bands. A quantum mechanical analysis was carried out to obtain the harmonic force field.
