Close collaboration over 25 years between laboratory spectroscopists and astrophysicists has allowed the detection of about one hundred different molecular species in the interstellar medium, largely via their rotational emission spectra. This interaction between spectroscopy and astrophysics was initiated in the 19th century to assign the Fraunhofer lines in the solar spectrum to atomic transitions. The first detection of molecular species (CN, CH, CH+) was made during the 1930s via their optical absorption spectra in diffuse molecular clouds. The author discusses developments in high resolution rotational spectroscopy in relation to astrochemistry and interstellar detections. Some results concerning planetary and cometary atmospheres are also presented. Finally the future projects mostly related to submillimetre and far infrared astronomy are presented.
