2060 Chiron has shown activity at heliocentric distances larger than 11 AU. To investigate the nature of the acitivity of this peculiar pbject, Chrion was observed during it approach to perihelion from June 1995 to January 1996. Observations at millimetre wavelengths were made at the IRAM 30 m telescope in June, September, and November 1995. Emission lines of CO, HCN, HCO and HS were searched for. On 25-28 January 1996, spectra of Chiron were obtained with the 2.2 m telescope at ESA, La Silla, from 3550 to 4750 Å to search for possible emission features, for example CN. No molecular signal was detected. Upper limits on the gaseous species observed are presented.
