It is shown that the deconvolution method of Van Cittert can be used reliably to enhance the effective spectral resolution by a factor of ∼3 with data that exhibit a high SNR (∼103) and in which base line variations have been eliminated. Deconvolution of a Doppler-limited spectrum of C6H6 measured on a difference-frequency laser system yielded linewidths of ∼1.2 × 10−3 cm−1 (compared with the Doppler width of 3.6 × 10−3 cm−1 at 203 K). Extensive reliability tests of the deconvolution technique have been performed.
