The vibration-rotation spectrum of HDO in the 2400-3300-cm(-1) region has been studied at 0.01-cm(-1) resolution with a Fourier transform spectrometer. Values of the ground state levels and levels in the (100) and (020) states have been determined from the data. The ground state levels are fitted to a Watson-type Ham-iltonian from which 17 rotational constants are obtained. Measurements of the strengths of over 1100 lines have been made using a nonlinear least-squares fitting technique, and 548 of these lines are analyzed to determine the band strengths, the coefficients of the F factors, and the Coriolis interaction parameters. The strengths of the A- and B-type (100) bands and the A- and B-type (020) bands are 53.2 +/- 0.9, 0.43 0.07, 6.00 +/- 0.54, and 2.75 +/-0.12 cm(-2) atm(-1) at 296 K, respectively.
利用傅里叶变换光谱仪，在2400 - 3300 cm⁻¹区域以0.01 cm⁻¹的分辨率研究了HDO的振转光谱。根据这些数据确定了基态能级以及(100)和(020)态的能级。基态能级被拟合到一个沃森型哈密顿量，从中获得了17个转动常数。使用非线性最小二乘法拟合技术对1100多条谱线的强度进行了测量，并对其中548条谱线进行分析，以确定带强度、F因子系数和科里奥利相互作用参数。在296 K时，A类和B类(100)带以及A类和B类(020)带的强度分别为53.2±0.9、0.43±0.07、6.00±0.54和2.75±0.12 cm⁻² atm⁻¹。
