✦ Synopsis

The high-resolution Raman spectra of the 4 bands of 11 B 2 H 6 and 11 B 10 BH 6 have been recorded and analyzed. The recordings have been made using a high-resolution spectrometer based on the inverse Raman effect. Q branches have been observed, but P and R branches were too weak to be seen, and simulations of the observed band contour have been necessary to complete the analysis. A weak Coriolis resonance with the 2 10 level is present in the 11 B 2 H 6 spectrum. The band centers obtained are 790.9829(12) and 804.76985(27) cm Ϫ1 for 11 B 2 H 6 and 10 B 11 BH 6 , respectively (uncertainties are type A with a coverage factor k ϭ 1, i.e., 1 standard deviation).
