摘要High-resolution and high signal-to-noise ratio spectra of Comet C/1995 O1 (Hale-Bopp), which provided continuous wavelength coverage from 5500 Angstrom to 8500 Angstrom and partial coverage from 4000 Angstrom to 5500 Angstrom, were obtained with the Coude Echelle Spectrograph at Beijing Astronomical Observatory on March 26, 28 and April 22, 1997. In the spectra we found 532 emission features, among which 459 lines frolrl H, O, Na, Ct, Cg, CN, CH, NH2 and H2O+ were identified. The intensity of sodium emission lines at 5890 Angstrom and 5896 Angstrom on April 22 increased about 5 fold compared to that recorded on March 26 and 28. The intensity ratio I-lambda 5577/(I-lambda 6300 + I-lambda 6364) of [O I] is consistent with the formation of excited O atoms from the photodissociation of H2O.
