The benzene spectrum in the nu(14) band near 1023 cm(-1) was investiga
ted by means of a pulse driven diode laser spectrometer with a resolut
ion of about 6 x 10(-4) cm(-1). We give individual absolute line stren
gths and air-broadening coefficients of 9 lines. The air-broadening co
efficients vary between 0.17 cm(-1)/atm and 0.23 cm(-1)/atm. These dat
a we used to estimate detection limits for a diode laser benzene detec
tion device. High resolution spectra of toluene were measured in the s
ame wavenumber region.
