The infrared spectrum of liquid water is dominated by the intense absorption due to the fundamental O-H stretching vibrations. Because of the high intensity, very short path lengths, usually less than 50 μm, are needed to record the spectra of aqueous solutions. Meer weergeven The absorption of electromagnetic radiation by water depends on the state of the water. The absorption in the gas phase occurs in three regions of the spectrum. Rotational transitions are … Meer weergeven The water molecule has three fundamental molecular vibrations. The O-H stretching vibrations give rise to absorption bands with band origins at 3657 cm (ν1, 2.734 μm) and 3756 … Meer weergeven The electronic transitions of the water molecule lie in the vacuum ultraviolet region. For water vapor the bands have been assigned as follows. • 65 nm band — many different electronic transitions, photoionization, • discrete features … Meer weergeven The water molecule, in the gaseous state, has three types of transition that can give rise to absorption of electromagnetic radiation: • Rotational transitions, in which the molecule gains a quantum of rotational energy. … Meer weergeven The water molecule is an asymmetric top, that is, it has three independent moments of inertia. Rotation about the 2-fold symmetry axis is illustrated at the left. Because of … Meer weergeven Absorption coefficients for 200 nm and 900 nm are almost equal at 6.9 m (attenuation length of 14.5 cm).
