Abstract
Tunable-infrared laser desorption in a time-of-flight mass spectrometer has been shown to be a viable technique for probing thin films. This technique has been used on a number of thin films, such as coronene and C$_{60}$. By tuning the infrared laser, resonance enhnacement could be seen from the change of signal intensity depending on the wavelength. The spectrum and possible mechanisms for this procedure will be discussed.
