The far-infrared spectrum of 2,5-Dihydrofuran has been recorded and it shows several ring-puckering transitions along with rotational-vibrational fine structure. Since the molecule is a near symmetric top (A = 0.267 cm-1 and B = 0.261 cm-1), the peaks are separated by approximately 0.53 cm-1. Despite the overlap between several puckering bands, the fine structure can be nicely resolved with a resolution of 0.1 cm-1. The ring-puckering spectrum consisting of a series of bands between 99 and 185 cm-1 is similar to that previously reported.
