在6500-16 400 cm−1范围内，利用高达800 m的路径长度和较长的积分时间获得了新的水蒸气傅立叶变换光谱。在这个波数范围内，这些光谱的信噪比明显高于以前的测量值。给出了13200 - 15000cm−1区域3604条谱线的波数、绝对强度和自展宽系数，它们都带有相关的不确定性。使用变分线列表对这些线进行了分析，并与以前研究中其他未分配的线一起进行了分析。这导致952条新的线分配到涉及35种不同的h216o的振动状态的过渡，少量的线分配到h218o和h217o。
Abstract New Fourier transform spectra of water vapor are presented in the range 6500–16 400 cm −1 obtained using pathlengths of up to 800 m and long integration times. These spectra have a significantly higher signal-to-noise than previous measurements in this wavenumber range. Wavenumbers, absolute intensities and self-broadening coefficients, all with associated uncertainties, are presented for 3604 lines in the region 13 200–15 000 cm −1 . Analysis of these lines using variational linelists, along with other unassigned lines from previous studies, has been conducted. This leads to 952 new line assignments to transitions involving 35 different vibrational states of H 2 16 O. A smaller number of lines are assigned to H 2 18 O and H 2 17 O.
