The possible mechanisms by which truly complex (ten or more atoms) hydrocarbon molecules can be synthsized in interstellar clouds are presented, including predictions by the gas phase and the grain surface synthetic models. The methods and the possibilities of detecting complex molecules in the microwave and millimeter, the infrared, and the ultraviolet/visible spectral ranges are discussed. Currently, low-resolution infrared studies offer best hope although, the difficulty of identifying the molecular carrier can be great. However, as the current receiver technology improves, the size of the molecules detected in the microwave and the millimeter ranges will be extended. Knowledge of the molecular sources of the individual ultraviolet and visible bands will aid in the identification of complex molecules in the observed interstellar spectra.
