Each compound has a specific absorption spectra.
There are a number of ways and it depends what you want to know (and already know) about the unknown compound. If it is an acid or a base, you can do a titration. If it is colored, you can measured the absorption spectrum by UV/Vis spectroscopy. If you have a good idea what the unknown compound could be (or a few options anyway), there may be a specific test for those particular compounds.
In spectroscopy, data is typically analyzed by measuring the intensity of light at different wavelengths. This data is then processed using mathematical algorithms to identify patterns, peaks, or changes in the spectrum that can provide information about the sample's composition, structure, or properties. Spectral data can also be compared to reference spectra or databases to aid in the identification of unknown samples.
I do not believe that any chemist would choose to identify a compound by using only the melting point; why create such difficulties for yourself?
Making an absolute identification of an unknown liquid means determining its exact chemical composition without any ambiguity. This typically involves using various analytical techniques such as spectroscopy, chromatography, and mass spectrometry to match the characteristics of the unknown liquid to known substances in databases.
To discover an unknown mineral, you typically need to analyze its physical and chemical properties using techniques such as X-ray diffraction, spectroscopy, and electron microscopy. Comparing the results to known mineral databases can help identify any matches or similarities, pointing towards potential mineral identification. Collaboration with experts in mineralogy and geology can also be valuable in determining and validating the discovery.
One can identify unknown substances through various methods such as conducting chemical tests, using spectroscopy techniques, analyzing physical properties, and comparing results with known substances.
In NMR spectroscopy, the chemical shifts of hydrogen atoms in a compound can help determine its cis or trans configuration. By analyzing the splitting patterns of the hydrogen signals, one can identify the relative positions of the hydrogen atoms and determine if they are in a cis or trans arrangement.

The significance of the NO2 infrared (IR) stretch in the analysis of a chemical compound lies in its ability to provide information about the presence of the nitro functional group. This stretch can help identify the specific chemical structure of the compound, as the NO2 group has a unique vibrational frequency that can be detected using IR spectroscopy.

In Chemthink Ionic Formulas, X represents an unknown element that you need to identify by determining the charge of the cation and anion in the ionic compound. By balancing the charges using X as the unknown element, you can deduce the correct formula for the compound.
IR spectroscopy works by using infrared beams to work out the structure of a chemical. The chemical is placed in an inert substance, e.g. Potassium Bromide. The refraction of the beams brings up a characteristic trace of the mystery compound, which can then be used to work out the structure.
Certified gemologists identify HPHT*-treated and HPHT-manufactured diamonds using specially developed spectroscopy devices. These devices facilitate measuring dispersed light shone through the diamond to reveal its generation.
