The ν1 and ν4 fundamental bands of H3Si37Cl investigated with high resolution

The present results, together with the accurate existing data for ν2, ν3, ν5, and ν6 bands, allowed us to derive the experimental values, Ae = 2.8722945(37) cm−1 and Be = 0.2182248(22) cm−1, which are compared with those of ab initio calculations.
