Is the following statement true or false? The IR spectroscopy requires lower photon energies to cause transition between levels than microwave spectroscopy. False, the microwave spectroscopy requires less energy to cause transitions since energy levels accessible in microwave spectroscopy are close together. True, the microwave spectroscopy requires more energy to cause transitions since energy levels accessible in microwave spectroscopy are further apart. False, only levels accessible in UV-vis spectroscopy are far apart, all other levels are very close together False, all these transitions are forbidden by selection rules. The presence of repulsion between electrons in multi-electron problem is the reason for a lack of an analytical solution of Schrodinger equation. Numerically this problem can solved by introduction of the following approximation A) separation of nuclear and electronic degrees of freedom B) Bohr atomic model C) assumption that each of the electrons moves in an average field caused by other electrons D) de Brogile formula E) A+C F) B+A G) None of the above
