The infrared spectra (IR) of pure liquid light (H(2)O) and heavy (D(2)O) water were obtained with attenuated total reflection (ATR) and transmission measurements in the mid-IR and far-IR. With these and with other values obtained from the literature, the real (n) and imaginary parts (k) of the refractive index were meticulously derived in the complete IR region from 6000 to 0 cm(-1). The reliability of the results resides in the critical comparison of our experimental data with that obtained from other laboratories and between calculated and experimental spectra, obtained by ATR and transmission techniques. The new optical properties (n and k) can now be used as standards for liquid H(2)O and D(2)O. To these we have added the water (H and D) absorption coefficients (K) that are derived from the k values. These can be used as references for spectra obtained by transmission with an absorbance intensity scale because they are almost the same.
获得了纯液态轻（H(2)O）和重（D(2)O）水的红外光谱（IR），采用衰减全反射（ATR）和中红外和远红外透射测量。利用这些数据以及从文献中获得的其他值，我们在完整的 IR 区域（6000 至 0 cm(-1)）中精心推导了折射率的实部（n）和虚部（k）。结果的可靠性在于对我们的实验数据与其他实验室获得的数据以及通过 ATR 和透射技术获得的计算和实验光谱之间的严格比较。新的光学特性（n 和 k）现在可以用作液态 H(2)O 和 D(2)O 的标准。我们还添加了从 k 值推导出来的水（H 和 D）吸收系数（K）。由于它们几乎相同，因此这些吸收系数可用于透射光谱，作为吸光度强度刻度的参考。
