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).
