摘要：

The gas-phase absorption spectrum of hydroxymethylhydroperoxide (HOCH2OOH; HMHP) at 298 K was recorded in the range from 205 to 360 nm using a diode array spectrometer. The concentration of HMHP was determined by FTIR spectroscopy. Its corresponding atmospheric photodissociation rates for mid-latitudes at ground level are estimated to be similar to 2.7 x 10(-6) s(-1) for 30 degrees, 1.9 x 10(-6) s(-1) for 50 degrees and 8.4 x 10(-7) s(-1) for 70 degrees zenith angle.
