In IR spectrum we take percent transmittence on vertical axis and wavelength on horizontal axis, so the peaks come down i.e more the certain wavelength of IR have been absorbed more deep will be the peak that is less amount of light of that wavelength was transmitted.

Functional groups in an IR spectrum can be identified by looking for specific peaks or bands that correspond to characteristic vibrations of different functional groups. Each functional group has unique vibrational frequencies that can be matched to peaks in the spectrum, allowing for their identification.
In the IR spectrum of a compound containing a CC double bond, characteristic peaks can be observed around 1650-1600 cm-1 for the CC stretching vibration.
The characteristic IR spectrum stretches of the functional group present in the compound can be identified by analyzing the peaks in the infrared spectrum. Each functional group has specific peaks that correspond to the vibrations of the bonds within that group. By comparing the peaks in the spectrum to known values for different functional groups, the presence of a particular functional group can be determined.
Infrared (IR) spectrum peaks are broader than nuclear magnetic resonance (NMR) spectrum peaks because IR is sensitive to molecular vibrations which are affected by multiple bonds in different environments, leading to a range of frequencies being absorbed. On the other hand, NMR is based on the magnetic properties of nuclei in a fixed magnetic field, resulting in specific resonances corresponding to unique atomic environments, hence producing sharper peaks.
In the benzophenone IR spectrum, characteristic peaks are typically observed around 1700-1600 cm-1 for the carbonyl group (CO) stretch, and around 1600-1500 cm-1 for the aromatic ring stretching vibrations.
The force constant is a measure of the strength of a chemical bond. In IR spectroscopy, it affects the vibrational frequency of a molecule, which determines the position of peaks in the IR spectrum. Higher force constants result in higher vibrational frequencies and shifts IR peaks to higher wavenumbers.
Organic liquids must be dried before running an IR spectrum to remove any water or solvents present in the sample. Water and solvent peaks may overlap with the peaks of interest in the IR spectrum, interfering with the analysis and leading to inaccurate results. Additionally, the presence of water or solvents can affect the baseline of the spectrum, making it difficult to interpret the data.
In a benzophenone IR spectrum analysis, key features include peaks at around 1700-1600 cm-1 for the carbonyl group, peaks at around 1600-1500 cm-1 for aromatic CC bonds, and peaks at around 3000-2800 cm-1 for C-H bonds.
The characteristic peaks observed in the vanillin IR spectrum are typically around 3400-3200 cm-1 for the O-H stretch, 1700-1600 cm-1 for the CO stretch, and 1300-1000 cm-1 for the C-O stretch.
The characteristic peaks observed in the salicylamide IR spectrum are typically around 3300-3500 cm-1 for the O-H stretching vibration, around 1680-1700 cm-1 for the CO stretching vibration, and around 1600-1620 cm-1 for the CC stretching vibration.
An IR spectrum of a compound is recorded by passing infrared radiation through a sample of the compound and measuring the absorption of different wavelengths by the sample. The resulting spectrum displays peaks and troughs corresponding to different functional groups present in the compound, which provides information about its structure and composition.
The majority of the sun's rays are in the visible light portion of the electromagnetic spectrum. This includes colors like red, orange, yellow, green, blue, and violet that we can see.
