Calculate the bond length of the OH molecule in the gas phase if the first two lines of the microwave spectrum occur at 8.562 cm1 and 17.124 cm.SOLVE STEP BY STEP IN DIGITAL FORMAT Explain the underlined paragraph, make it extensive and unambiguous, support its foundations in biochemistry and quantum mechanics. The sample substance used is 1,1-diphenyl-2-picryl-hydrazyl (DPPH). This organic compound is a relatively stable free radical which has an unpaired valence electron at one atom of the nitrogen bridge. The orbital motion of the electron is almost cancelled by the molecular structure. Therefore the g-factor of the electron is almost equal to that of a free electron. In its polycrystalline form the substance is very well suited for demonstrating electron spin resonance because it has an intense ESR line, which, due to exchange narrowing, has a small width.7) Explain the basis of the Franck-Condon principle and how it leads to the formation of a vibrational progression.
