High resolution study of MGeH4 (M=76, 74) in the dyad region

High resolution study of strongly interacting ν1(A1)/ν3(<

“…[7]. Briefly, an enriched and purified sample of germane containing 76 GeH 4 (88.1%), 74 GeH 4 (11.5%), 73 GeH 4 (0.07%), 72 GeH 4 (0.17%), 70 GeH 4 (0.12%) was spectroscopically studied using a Brucker IFS125HR Fourier transform spectrometer (Nizhny Novgorod, Russia).…”

“…In this case, energy values of the ground vibrational state were calculated with the parameters from Ref. [7]. As a result of assignment, about 310 and 280 transitions were assigned to the ν 3 , ν 1 bands of 76 GeH 4 .…”

“…For that reason, laboratory investigations of high resolution spectra of germane are interesting and important (the review of earlier spectroscopic studies of germane can be seen in our recent paper, Ref. [7]). …”

“…[7][8][9], of germane high-resolution spectra in the region of the ν 2 =ν 4 dyad. Here, our attention is focused on the pair of strongly interacting stretching bands ν 3 and ν 1 .…”

“…rotational energies of the ground vibrational states from Ref. [7], the ro-vibrational energies of the ð1000; A 1 Þ and ð0010; F 2 Þ vibrational states of 76 GeH 4 and 74 GeH 4 were determined. They are presented in columns 2 and 4 of Tables 3 and 4.…”
