After an induced absorption process of an intensity, there are (without population inversion) transitions between:a) vibrational and rotational levels in the infrared region, we obtainb) vibrational levels exclusively in the infrared regionc) vibrational and rotational levels in the microwave regiond) transitions between nuclear spin levels in the radio frequency region
In a spontaneous emission process:a) the ground state population decreasesb) the excited state population decreasesc) the non-radiative component is predominantd) the emitted radiation is coherent
For a molecule there are 3 energy levels A, B and C, where B is an intermediate energy level between A and C. The A → C transition occurs at 480 nm and the B → C transition occurs at 885 nm. Indicate the wavelength at which the A → B transition will occur.
