Abstract

Measurements of the absorption and fluorescence excitation spectra in a supersonic free jet are performed simultaneously with the use of a dc Xe lamp and lock-in detection. With this inexpensive equipment it is possible to measure spectral features from UV to VIS with absorbances as low as 5×10^-6 and with a spectral resolution of 0.9 Å. Absorption and fluorescence excitation spectra of 9-cyanoanthracene, which is solid and nonvolatile under ambient conditions, are presented Achievable signal-to-noise ratios are theoretically calculated and experimentally verified.
