Infrared (IR) spectroscopy is one of the most common spectroscopic techniques used by organic and inorganic chemists. Simply, it is the absorption measurement of different IR frequencies by a sample positioned in the path of an IR beam. The main goal of IR spectroscopic analysis is to determine the chemical functional groups in the sample.

produced by machine or workpiece deflections, vibrations, and other ir­ regularities in the cutting process. Roughness is an ideal effect that results from the geometry of the tool, feed, speed, feed-speed interac­ tion, and the condition of the plastic flow of the material removed.

The IR spectrum shows several signals, most importantly an intensive signal at 3000 cm −1, corresponding to a NH vibration, a shifted CO vibration at 1655 cm −1, and shifted CN vibrations at 1536 as well as at 1247 cm −1 (Figure 2). Elemental analysis reveals a hydrogen content of 4.23 %, which is more than the theoretical value of 3 % ...

A mode of vibration can be defined as a way of vibrating, or a pattern of vibration, when applied to a system or structure that has several points with different amplitudes of deflection. A mode of vibration comprises two distinct elements: first, a time variation of the vibration and, second, a spatial variation of the amplitude of the motion across the structure.

Vibrating bonds absorb infrared energy at a frequency that corresponds to the vibrational frequency of the bond. In organic chemistry, this corresponds to frequencies of 15 to 120 THz. These frequencies are expressed as wavenumbers: wavenumber = frequency speed of light = ν c. So the wavenumbers range from 500 to 4000 cm⁻¹.

Vibration is most commonly measured using a ceramic piezoelectric sensor or accelerometer. An accelerometer is a sensor that measures the dynamic acceleration of a physical device as a voltage. Accelerometers are full-contact transducers typically mounted directly on high-frequency elements, such as rolling-element bearings, gearboxes, or spinning …

A ball mill also known as pebble mill or tumbling mill is a milling machine that consists of a hallow cylinder containing balls; mounted on a metallic frame such that it can be rotated along its longitudinal axis. The balls which could be of different diameter occupy 30 – 50 % of the mill volume and its size depends on the feed and mill size.

IR rays strike the grains and induce a vibration in the molecules of the host, this results in the generation of intermolecular friction due to which rapid heating takes place ( Deepa & Hebbar, 2016 ). In case of legumes, IR heating of the whole grains leads to deformation in the gums and pectin sandwiched between the hull and cotyledons.

A molecule is IR active if it has a permanent dipole moment; HCl is active while N 2 is inactive. IR spectrum represents the rotation-vibration spectrum of the molecule. In solution, the rotation of molecules is strongly hindered, bands are strongly broadened and the maxima of these bands correspond to the

FT-IR spectrum analysis. The functional groups and chemical bonds of PZMP4 were further analyzed by FT-IR (Additional file 1: Fig. S1A). The O–H-stretching vibration and the C–H-stretching vibration were represented by distinct bands in the 3411 and 2937 cm −1 regions, respectively.

• Vibrations in IR spectroscopy also known as fundamental vibrations. • The IR spectroscopy concept can be generally analysed in 3 ways: * By measuring reflection * By measuring emission * By measuring absorption • It is an important qualitative analytical technique for determining the structure of both organic & inorganic compounds.
