Document Summary

Che 113- lecture 19- forensic chemistry continued & medicinal chemistry. When you have a molecule and light hits it and excites it. The specific amount of energy needed to excite the molecule is specific to that molecule and is used to id that certain molecule. Start with an electron with a low amount of energy. Add energy to reach a certain point. Calculate the amount of energy it took to reach that certain point. When white light passes through or is reflected by a colored substance, a characteristic portion of the total wavelengths is absorbed. The remaining light will assume the complementary color to the wavelength/s absorbed. This is how we see all the colors within the color wheel. Protons excite an electron to a higher energy level (orbital) Of the six transitions outlined, only the two lowest energy ones have enough energy to be excited.
