文摘
- •
data analysis was analyzed by Voigt deconvolution method.
- •
each spectral line consists of a superposition of two bands.
- •
Competition between the Gaussian and the Lorentzian width was evident in figures (5,6,7).
- •
The width ratio () reveals the issue of competition between thermal and collisional effects.
- •
Voigt FWHM was always a linear function with the pressure at 298 K, 323 k and 348 K, but at 373 K does not.
