在波长分辨率为0.06-0.11A(∼7-12 cm−1)的650-990A波长范围内，测量了H2O和D2O的室温和旋转冷却相对光电离截面，并将光谱归一化为Katayama等人测定的绝对光电离截面。题名/责任者：Reach for[D H.太棒了。59,4309(1973)]较低的分辨率。对(A2 A1)3DB11B1ΠX1A1里德堡跃迁(0，6，0)和(0，8，0)带的←子带的转动分析确定了上态的对称性，并将级数推广到更高的主量子数.由于转动跃迁的自然线宽很大，以及没有到N‘≳3转动能级的跃迁，这些和其他谱带的分析都变得困难。
Room temperature and rotationally cooled relative photoionization cross sections for H2O and D2O were determined in the wavelength region 650–990 A with a wavelength resolution of 0.06–0.11 A (∼7–12 cm−1 ); the spectra were normalized to the absolute photoionization cross sections determined by Katayama et al. [D. H. Katayama, R. E. Huffman, and C. L. O’Bryan, J. Chem. Phys. 59, 4309 (1973)] with lower resolution. A rotational analysis of the Π subbands in the (0,6,0) and (0,8,0) bands of the (A 2A1)3db11B1←X1A1 Rydberg transition determined the symmetry of the upper state; in addition, the series was extended to higher principal quantum numbers. The analysis of these and other bands was made difficult both by the large natural linewidths of the rotational transitions and by the absence of transitions to rotational levels with N’≳3.
