High-resolution broad-bandwidth Fourier-transform absorption spectroscopy in the VUV range down to 40 nm

Vacuum-ultraviolet (VUV) high-resolution absorption spectroscopy is a unique tool for the study of gas-phase atomic and molecular electronic structure. To date, it has been performed by using lasers or synchrotron radiation-based grating spectrometers, but none of these techniques can offer simultaneous high resolution, wavelength accuracy and broad tunability. The only technique combining these three important features is Fourier-transform...
