The CMPD Crime Lab is the forensic services division of the Police Department. The Crime Lab’s job is to scientifically test evidence that is collected as part of criminal investigations to determine what type of information can be gathered from the evidence. Evidence can be tested in a variety of different ways depending on the ...

WebImaging spectrometers are used specifically for the purpose of measuring the spectral content of light and electromagnetic light. The spectral data gathered is used to give the … Infrared spectroscopy (IR spectroscopy or vibrational spectroscopy) is the measurement of the interaction of infrared radiation with matter by absorption, emission, or reflection. It is used to study and identify chemical substances or functional groups in solid, liquid, or gaseous forms. It can be used … See more Infrared spectroscopy exploits the fact that molecules absorb frequencies that are characteristic of their structure. These absorptions occur at resonant frequencies, i.e. the frequency of the absorbed radiation matches … See more IR spectroscopy is often used to identify structures because functional groups give rise to characteristic bands both in terms of intensity and position (frequency). The positions of these … See more Infrared spectroscopy is a simple and reliable technique widely used in both organic and inorganic chemistry, in research and … See more Two-dimensional infrared correlation spectroscopy analysis combines multiple samples of infrared spectra to reveal more complex properties. By extending the spectral information of a perturbed sample, spectral analysis is simplified and resolution is … See more The infrared spectrum of a sample is recorded by passing a beam of infrared light through the sample. When the frequency of the IR is the same as the vibrational frequency of a bond or collection of bonds, absorption occurs. Examination of the … See more The different isotopes in a particular species may exhibit different fine details in infrared spectroscopy. For example, the O–O stretching frequency (in reciprocal centimeters) of oxy See more • Applied spectroscopy • Astrochemistry • Atomic and molecular astrophysics See more fishnet sleeveless sweater
