I am curious what prompted the Authors to deal with N-H...O bonding in place of the earlier O-H...O.
In this article, the authors describe the spectral characteristics of NH in the hydrogen bridge NH...O. It is a continuation of similar OH...O binding studies performed 10 years ago. The rationale for undertaking the research is a bit puzzling. I am curious what prompted the Authors to deal with N-H...O bonding in place of the earlier O-H...O. The explanation should be cleared.
