Influence of aprotic solvents on the O–D stretching band of methan[2H]ol
Abstract
The O–D stretching band of methan[2H]ol has been observed for 0.4M-solutions in 55 aprotic solvents, including hydrocarbons, halogeno-compounds, nitro-compounds. nitrites, ethers, ketones, esters, amines, and amides. Values of vOD for monomeric methan[2H]ol have been measured as precisely as possible. Various discrepancies with earlier work are noted. The values of vOD are discussed in terms of solvent Lewis basicity, and revised values of Koppel and Palm's solvent parameter B are tabulated. Oligomer formation and the occurrence of anomalous bands in the case of certain solvents are also discussed. A more limited study was made of the O–D stretching band of t-butyl [2H]alcohol.
