我们使用高分辨率相干反斯托克斯拉曼光谱测量的温度分布和压力的充氮钨灯。使用修正的指数能隙模型的J依赖的碰撞增宽系数，我们得到了很好的拟合实验光谱，产生空间分辨的温度和压力的精度为+/-5%。
We use high-resolution coherent anti-Stokes Raman spectroscopy to measure the temperature profile and pressure in a nitrogen-filled tungsten lamp. Using a modified exponential-gap model for the J-dependent collisional-broadening coefficients, we obtain good fits to the experimental spectra, yielding spatially resolved temperatures and pressures with an accuracy of +/-5%.
