The side chain is a hydrocarbon branching element of a molecule that is attached to a larger hydrocarbon backbone. It is one factor in determining a molecule's properties and reactivity. [ 2 ] A side chain is also known as a pendant chain , but a pendant group (side group) has a different definition.
In radio communications, a sideband is a band of frequencies higher than or lower than the carrier frequency, that are the result of the modulation process. The sidebands carry the information transmitted by the radio signal. The sidebands comprise all the spectral components of the modulated signal except the carrier.
The spectrum of a particular molecule is governed by the selection rules of quantum chemistry and by its molecular symmetry. Some molecules have simple spectra which are easy to identify, whilst others (even some small molecules) have extremely complex spectra with flux spread among many different lines, making them far harder to detect.

In organic chemistry, a methyl group is an alkyl derived from methane, containing one carbon atom bonded to three hydrogen atoms, having chemical formula CH 3 (whereas normal methane has the formula CH 4). In formulas, the group is often abbreviated as Me. This hydrocarbon group occurs in many organic compounds. It is a very stable group in ...
Side-chain, side chain, or sidechain may refer to: Side chain, a chemical group attached to the main chain or backbone of a molecule, such as a protein; Substituent, an atom or group of atoms substituted in place of a hydrogen atom on the parent chain of a hydrocarbon; Side-chaining, an effect in digital audio processing
In solid-state physics, the valence band and conduction band are the bands closest to the Fermi level, and thus determine the electrical conductivity of the solid. In nonmetals, the valence band is the highest range of electron energies in which electrons are normally present at absolute zero temperature, while the conduction band is the lowest range of vacant electronic states.
A side band or sideband can refer to: Side project, in music; Sideband, in communications, either of the two bands of frequencies, one just above and one just below a carrier frequency, that result from modulation of a carrier wave
Figure 1: Measured strain distribution of a tensile test (shape memory alloy) during loading and unloading shows moving Lüders bands. The measurement was performed with a LIMESS Digital image correlation system. As internal stresses tend to be highest at the shoulders of tensile test specimens, band formation is favored in those areas.
