Abstract

We describe an apparatus for the measurement of slow rotational diffusion based on the phosphorescent photoluminescence of the triplet probe, erythrosin, and using phase modulation techniques. The apparatus has two novel features over those previously described: up to 40 frequencies of modulation are collected simultaneously, and the superimposition of fast 0-100% modulation of the excitation laser beam enables contaminating prompt fluorescence to be removed by time domain resolution during the frequency domain resolution of phosphorescence.
