The collision broadening and shift of the Hg intercombination spectral line 253.7 nm (61S0–63P1) perturbed by Kr has been investigated using a high-resolution scanning Fabry–Perot interferometer. The values of the pressure broadening and shift co

The classical theory of collisional broadening and shift parameters ( β , δ ) of an isolated spectral line was used to obtain simple analytical formulas for calculating both β and δ . These formulas were obtained on the assumption that the short

The temperature dependence of the Cd line absorption profile at 326.1 nm perturbed by Kr has been carefully studied over a spectral range extending from 800 cm−1 in the blue wing to 1200 cm−1 in the red wing using a high-resolution double-beam sp

A set of intercombination rules has been used to calculate the two excited (30 and 31) state potential parameters e12 and R12 of Hg, Cd and Zn interacting with inert gases (Xe, Kr, Ar and Ne). The results obtained with these rules are compared with v

Aerosols are minute particles suspended in the atmosphere. When these particles are sufficiently large, we notice their presence as they scatter and absorb sunlight. They scatter and absorb optical radiation depending upon their size distribution, re
