The finding of the blue-shifted F-He-H... Y (Y=N〓, CO and He) systems, where the proton-donor was incapable of rehybridization, indicated that rehybridization is not a generally application driving force for the blue shift. There were other two novel blue-shifted systems discovered in this study. They were lithium bonding systems and dihydrogen bonding systems. On the basis of state-of-art NBO analyses and potential energy surface analysis, it was demonstrated that Pauli/nuclei repulsions cause the blue shift.
