After 90 MPa hydrogen exposure, the time resolved infrared spectroscopy and the hydrogen content measurement for bisphenol A polycarbonate (PC) during hydrogen desorption process were conducted. The foreign peak at 4125 cm−1 in the infrared spectra of high-pressure hydrogen exposed PC was observed. Judging from the proportion of the absorbance of the peak to hydrogen content and the molar concentration of the penetrated hydrogen in PC, the peak was assigned to the H-H stretching of penetrated hydrogen molecule in PC. The hydrogen molecule is considered to be isolated by the PC molecular chain.
