Hydrogen bond equilibrium constants for the complexes of benzotriazole and some nucleoside derivatives. A near infrared study.
Approximate hydrogen bond association constants were determined by near infrared spectroscopy for pairs formed by benzotriazole and a number of nucleoside derivatives. The molecule of benzotriazole forms, in chloroform, hydrogen bonds with inosine, uridine and adenosine derivatives. The order of decreasing association constants for complexes formed by benzotriazole and uridine or inosine derivatives is the opposite of the one observed for pairs formed by adenosine and uridine or inosine derivatives.
