Why are $NaCl$ plates used instead of quartz plates in IR spectroscopy to load sample?

$""^13"C"$ NMR spectroscopy was developed after $""^1"H"$ spectroscopy because the technology was not yet available. 99.99 % of the H atoms in a compound are $""^1"H"$. Even so, the NMR...

...... whereas, $"IR spectroscopy"$ examines molecular transitions. The most common (and most sensitive) form of $"NMR spectroscopy"$ is $""^1"H"$ $"NMR spectroscopy"$. And this examines nuclear transitions. A proton, an hydrogen...

There's the old way and the new way. The Old Way "They" would periodically take an infrared spectrum of the sample and compare it with a spectrum of the...

The length and tightness of a bond determines the frequency at which a certain bond will resonate/vibrate. (Compare this to strings in sound). Each frequency corresponds to a wavelength (colour)...

I can remember some of the older organic profs at university, who were remarkably proficient in the identification and interpretation of IR spectra. When I asked them why they were...

It is a very common and useful analytical technique used in a wide variety of studies. Applied to forensics it is most often used to identify organic compounds that may...

IR-frequency light is passed through a compound. The amount and frequencies of the light absorbed is related to the functional groups and structure of the compound. This helps us to...

From the spectrum, we can identify the functional groups present in the compound. There is a reference table which has data on the absorption range of different functional groups....

Consider the main point of IR. What you're doing in IR spectroscopy is disturbing the motion of molecules with resonant frequencies to make them stretch and bend more intensely. Do...
