WebJun 20, 2024 · The 2.4-GHz and 5-GHz frequency bands support a limited number of non-overlapping 20-MHz and 40-MHz channels. Wi-Fi 5 and Wi-Fi 6 (802.11ax) standards added support for an 80-MHz and 160-MHz channel width to allow for higher data speed. But in practice, the wider channels are rarely deployed. 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 cm (ν3, 2.662 μm) in the gas phase. The asymmetric stretching vibration, of B2 symmetry in the point group C2v is a normal vibration. The H-O-H bending mode origin is at 1595 cm (ν2, 6.269 μm). Both symmetric stretching and bending vibrations have A1 symmetry, but the frequency difference be…
