By using a Raman spectrometer system whose absolute sensitivity is calibrated, we have measured the absolute Raman scattering cross sections of trimethylgallium (TMG) and trimethylaluminum (TMA) in the vapor phase. The measured cross sections are (dtr/dl2)~sXM~ = 1.3 Γ 10 -29 cm2/molecule sr line an

Methyl (CH 3) is generated by photodissociation of methyliodide (CH3I) applying an excimer laser operating at 248 nm. The ca 3 is detected using coherent anti-Stokes Raman spectroscopy (CARS). The CH 3 density is deduced by monitoring simultaneously the reduction of the CARS signal of the parent mol
