Description

General description

The microwave spectrum of 5-methylthiazole was investigated by employing both Fourier transform and Stark spectroscopy. 5-methyl thiazole undergoes alkylation with n-butyl bromide followed by anion exchange of Br^- for BF₄^- to give mobile, room-temperature ionic liquids.
