| 摘 要： | 尽管红外微光谱有广阔的用途,但是由于光学规则与实际设计的局限性,其基本的空间分辨率受到了限制.傅里叶变换红外光谱的空间分辨率局限于3倍的红外辐射波长.通过使用衰减全反射(ATR)的方式,可以将其空间分辨率接近于其辐射波长.纳米级红外光谱(Nano IR)技术可以解决分辨率的限制,提供一种在200 nm及其之上可以测量样品物理和化学性质的方法.

| Abstract: | Despite its widespread applications, infrared microspectroscopy has fundamental spatial resolution limits set by both the laws of optics and practical design constraints. Fourier transform infrared spectroscopy is generally limited to a spatial resolution of three times the wavelength of the IR radiation. With attenuated total reflection （ATR）, it may be possible to achieve resolution approaching the wavelength of the radiation. The nanoIR？ technique breaks new resolution limits, providing both chemical and physical property data on the scale of ~200 nm and beyond. |
