Concentration, acidity, specific ultraviolet absorbance (SUVA254) and molecular weight distribution (MWD) of these fractionations were analyzed.

The UV absorption properties of these compounds in polyethylene glycol film indicate that they have suitable absorption and transparency at 193 nm wavelength.

Influence of polydispersity on UV absorption spectra of ZnO nanoparticles, which were prepared from zinc bromide and sodium hydroxide as well as zinc acetate and sodium hydroxide in 2-propanol, had been studied.

The UV absorption of α hydroxy α,α dimethyl ( p hydroxyethyloxy) acetophenone(HMHOAP), α hydroxy α,α dimethyl acetophenone(HMAP) and α,α dimethoxy α phenyl acetophenone(DMAP) in different media was investigated.

Experimental study on temperature dependence of ultraviolet absorption cross-sections of sulfur dioxide;

Using various alcohols as solvents,it was determined that the ultraviolet absorption energy(ΔE)values of conjugated bond for fructus gardeniae flavochrome,and the relationship between the ΔE values and the molecular structures of alcohols was discussed.

Using a series of alcohols as solvents, the ultraviolet absorption energy ( AE) values of carbonyl (C = 0) for acetone and cyclohexanone were determined.
