Gas phase basicities of 1,3-benzazoles: benzimidazole, benzoxazole, benzothiazole, benzoselenazole and benzotellurazole
Abstract
The gas phase basicities of the title compounds have been experimentally determined by means of Fourier transform ion cyclotron resonance spectroscopy (FTICR). The experimental results have been analysed further using the PM3 semiempirical MO method.
