In this work, the optical properties (absorption, absorption coefficient, refractive index, band- gap energy, extension coefficient, and reflection) of the five samples of isonitrosoacetophenone (C8H7NO2) was studied using Uv-Vis spectroscopy. The C8H7NO2 was dissolved in different amounts of (0.5, 1, 1.5, and 2) ml of distilled water. The effect of concentration on the optical properties of C8H7NO2 was investigated experimentally and it was shown that the different values of the calculated optical properties are clearly affected by the concentrations of the C8H7NO2 compound. In addition, when the isonitrosoacetophenone is mixed with 2.0 ml of water the absorbance rate of the pure isonitrosoacetophenone was shown to be decreased from 2.7×10-4 (a. u.) at 278 nm to 1×10-4 (a. u.) at the same wavelength. Furthermore, the transmission of C8H7NO2 was shifted towards the shorter wavelength as the concentration of water is increased, which is starts from ~346 nm for pure isonitrosoacetophenone and decreased to ~ 300 nm when mixed with 2.0 ml of water. The important finding of this work was that the compound C8H7NO2 is opaque (non-transmittance) material from the wavelength of 220 to 300 nm which corresponds to the UV portion of the electromagnetic spectrum and this suggests more study in this area.
