Abstract

The high resolution Raman spectra of the Ņ4 bands of 11B2H6 and 11B10BH6 have been recorded and analyzed. The recordings have been made using a high resolution spectrometer based on the inverse Raman effect, with an instrumental resolution of 0.007 cm-1. Only Q-branches have been observed, and simulations of the observed band contour have been necessary to complete the analysis. A weak Coriolis resonance with the 2 Ņ10 level is present in the 11B2H6 spectrum. The band centers obtained are 790.9829(12) cm-1 and 804.76985(27) cm-1 for 11B2H6 and 10B11BH6, respectively (uncertainties are type A with a coverage factor k=1).
