The high-resolution infrared spectrum of $CH3F$ isolated in solid parahydrogen is studied via FT-IR methods. The $CH3F$ doped parahydrogen crystals are prepared using the rapid vapor deposition method developed by Fajardo and co-workers. $CH3F$ was studied as a prototypical symmetric top molecule in a quantum cavity. The infrared spectroscopy suggests $CH3F$ undergoes nearly free rotation indicating it occupies a single substitution site. Spectroscopic results and analysis on the $CH3F$ rovibrational dynamics and nuclear spin relaxation will be presented.
