2.吸光度（Absorbance）：吸光度表示样品对光的吸收程度。在FTIR中，吸光度是通过测量样品和参考（如空气或背景）之间的光强度的差异来获得的。3.透过率（Transmittance）：透过率是样品透过的光强度与入射光强度的比值。在FTIR中，透过率用于表示样品对特定波长光的吸收能力。4.分辨率（Resolution）：

The thermal decomposition of crystalline europium hydroxide has been studied by dynamic (differential thermal analysis and thermogravimetry) and static (fourier transform infrared and high-resolution photoluminescence spectroscopies) methods. It was deduced that crystalline europium hydroxide was thermally stable...
High-resolution (Doppler-limited) infrared absorption spectra of the 26 0 1 band of cyclopentadiene (C 5H 6) have been recorded with FTIR and diode lasers. In addition to room temperature measurements, diode laser spectra were also recorded in a molecular jet. The latter experiments were ...
