We propose one new concept of "aging of molecules" with no apparent structural changes, which is different from the traditional one with the breaking of chemical bond. Now, IR spectra for the traditional water molecules were changed after long-term electron impact and different potential treatment. Moreover, the performance for hydrogen evolution reaction (HER) using water solution after treatment was decreased obviously. The Density Functional Theory (DFT) calculations indicated the lower activity for HER is origin from comes from the shortened O-H bond length. We hope the construction of new instrument platform with ultrahigh sensitivity and resolution and new theoretical model describing new aging molecules can induce positive effect in energy and life area.
