Abstract The high-resolution spectrum of the ozone a-type hot band [nu][sub 3]--[nu][sub 2] in the region 290--380 cm[sup [minus]1] has been recorded with a Bruker IFS 120 HR interferometer. A procedure based on absolute pressure measurements has been developed to determine the initial ozone particle density. The decomposition in the White-type absorption cell was monitored employing relative linestrength data from the sequence of individual spectra within the measurement. Experimental line positions and linestrengths of about 300 transitions were evaluated. A vibrational transition moment [mu](001)-(010) = [minus]0.019044(64) D was obtained from the experimental linestrengths by means of a least-squares fitting procedure. The fit was rather satisfactory since the experimental data were reproduced within their average uncertainty of 12%. From the reduced data, linestrengths can be predicted with an accuracy of about 3--10%. The linestrengths of 26 transitions in the [nu][sub 2] band of ozone have been evaluated and compared with the HITRAN 92 database. The present values are on average 3.5 [+-] 3.1% smaller and thus in good agreement with the previous results.
