Scientific paper

Infrared line intensities for candidate parent molecules constituting cometary nuclei are evaluated, and many detectable lines are shown. The only mechanism considered is resonance scattering of the incident solar infrared radiation, but other infrared sources are taken into account, including zodiacal light, thermal emission from a cometary nucleus, and infrared continuum from dust in a coma. The molecular sublimation rate is determined in order to reveal the molecular abundances of cometary nuclei. The emissions from H2O, CO, CO2, CH4, and OH are particularly remarkable, from which the fluxes larger than 10 to the -17 W/sq cm are expected for a comet having a standard gas production rate of 1 10 to the 29th H2O/s at R = 1 A.U. = the comet-observer distance, where R is the heliocentric distance.
