空气中水汽的存在形式（Ｈ２Ｏ）ｎ与水汽红外光谱的复杂性 姚 蒙，王海水＊ 华南理工大学，广州五山 ５１０６４０ 摘 要 水汽（ｗａｔｅｒ ｖａｐ ｏｒ）是空气的组成部分，强极性的水汽对红外光有很强的吸收。水汽峰常常出现在样品的红外光谱上，对样品ＩＲ谱的识别和鉴定造成严重干扰。为消除水汽峰的不利...
calculation of the infrared (IR) spectra of complex systems, which combines the fragment-based Coupled Cluster method and anharmonic vibrational quasi-degenerate perturbation theory, and demonstrate its accuracy towards the complete and accurate assignment of the IR spectrum of the H+(H2O)21 cluster....
Using the reflected IR spectrum simplifies sample preparation. Reflection IR measurements of experimentally hydrated glasses show that the H 2 O content of basaltic, andesitic, and rhyolitic glasses can be quantified down to ≈0.5 wt.%. Lateral resolution is limited by intensities of current IR ...
The results of an implementation of a complex scientific project aimed at creating a data base of the H2O absorption line shift and broadening coefficients in the IR and visible regions of the spectrum are summarized. The experimental equipment and calculation methods used for obtaining quantitative ...
The IR spectra are dominated by the antisymmetric stretching mode of NO3−, which is doubly degenerate in the bare ion but splits into its two components for most microhydrated ions studied here due to asymmetric solvation of the nitrate core. However, for NO3−(H2O)3, the spectrum ...
The works cited just above make it evident that there is a direct connection between the IR vibrational frequency modes spectrum with the local force constant, and that in the context of hydrogen boning, a smaller force constant for the associated ‘donor’ covalent OH stretching mode would mean...
The spectrum has a prominent progression in the metal‐H2O stretching mode with a frequency (ω’ e ) of 518.0 cm−1. An extrapolation of this progression fixes the excited statedissociation energy (D ’ 0) at 15 787 cm−1. The corresponding ground state value (D ‘ 0) is 8514 ...
