Raman spectra are used for studying the structure and protein, nucleic acid, lipid, and carbohydrate contents, while cervical cancer cells irradiated by X rays of different doses are cultivated for 24 h. After irradiation by X rays, the following results are obtained. (1) Some 12-Gy groups move to the 1237-cm-1 band in compared with the control group’s 1240-cm-1 band; after irradiation by 6-Gy X ray, the 1662-cm-1 band of amide I has a blue shift of 10 cm-1 The above two parts show that because
