Abstract

The performance of a commercial rapid scanning spectrometer was checked experimentally in studies of flash photolysis, photochromism, phosphorescence, and thermal radiation. Rapid scan spectra (1 msec to 100 msec) were measured in portions of the uv, visible, and ir spectral regions (total wavelength coverage 250 nm to 14.5 μm), at rates up to 800 spectra/sec. The effect of grating line spacing on resolution and spectral range was measured. In absorption measurements, successive scans of the background radiation source were photometrically reproducible to within 1 part in 80. The effect of scanning time on resolution was studied experimentally; resolution of 0.94 cm⁻¹ at 2400 cm⁻¹ was achieved with signal-to-noise of 30:1, during rapid scanning. Recording on magnetic tape and oscillographic recording are illustrated.
