How to Read Power Spectra Frequently Asked Questions Q: Is FTIR affected by the environment? Q: How deep does the infrared light penetrate at the position of contact between the prism and sample during ATR meas
Mass spectrometers produce spectra which show intensity as a function of mass-to-charge ratio. This is done by ionising the sample, supplying the ions with kinetic energy, and directing them through a magnetic field. The ions are then deflected by the field. Those with a lower mass-to-charge...
molecular modelingmuscimolNMR in waterThe biologically active alkaloid muscimol is present in fly agaric mushroom ( Amanita muscaria ), and its structure and action is related to human neurotransmitter γ‐aminobutyric acid (GABA). The current study reports on determination of muscimol form present in...
Raman Spectroscopy is a non-destructive chemical analysis technique which provides detailed information about chemical structure, phase and polymorphy, crystallinity and molecular interactions. It is based upon the interaction of light with the chemical bonds within a material. Raman is a ligh...
One of the most versatile and useful types of IR spectrometers is the near-infrared (NIR) spectrometer, which covers wavelengths just beyond the visible, i.e., from 780 nm to 2500 nm. The theory of molecular spectroscopy: Spectroscopy is an analytical technique that uses the interaction of ...
background, excitation wavelength and the influence of laser power. For the purposes of this simple introduction, it is enough to note that Raman spectroscopy demands high stability monochromatic laser sources and high-sensitivity, low noise optics, which can acquire spectra with good resolution ...
Learn More Two-Photon Absorption and Upconversion Two-photon absorption (TPA or 2PA) is a nonlinear optical process in which a material absorbs two photons simultaneously (or within a very short timespan) to excite an electron from a lower-energy state to a higher-energy state. The total ene...
What is fluorescence spectroscopy and what advantages does this type of spectroscopy offer for analyzing fluorescence from a wide range of luminescent samples.
The scientific study of matter's characteristics and behaviour is known as chemistry. Chemistry vocabulary and Chemistry glossary are different from the normal vocabulary. It is a branch of natural science that examines the building blocks of matter, including the atoms, molecules, and ions that mak...
Infrared (IR) Spectroscopy can be used to monitor the progress of chemical reactions as the IR spectrum of a molecule is highly dependent on both atomic content and molecular structure. In addition, IR spectroscopy can be used to monitor isotopic substitution in molecules, as the force constant ...
