Abstract
The infrared spectra of 32 SF 6, 33 SF 6 and 34 SF 6 dimers were studied in argon and nitrogen matrices. The spectra of SF 6 dimers of like and unlike isotopomers were also calculated taking into account the resonance dipole–dipole and dipole-induced dipole interactions between two triply degenerate oscillators. Two absorption bands with site structure are observed for ( 32 SF 6) 2, ( 33 SF 6) 2 and ( 34 SF 6) 2 in argon; the ν X, Y band is blue shifted and the ν Z band is red shifted from the ν 3 SF 6 band in accordance with calculated spectra. Three and two components of the predicted quadruplets are identified for 32 SF 6– 34 SF 6, 32 SF 6– 33 SF 6 , respectively. In the spectra of (SF 6) 2 in nitrogen matrices the splitting of ν X, Y component of the resonance doublet was observed.
