What is epichlorohydrin?
According to Wikipedia, it's some pretty nasty stuff. They say its "flammable, toxic, and carcinogenic." So basically it blows up, kills you, AND gives you cancer. You may want to check out: http://en.wikipedia.org/wiki/Epichlorohydrin
How is glycerol formed?
There are two basic ways glycerol forms. The first is natural, by the combinaation of fats and oils. The second is by sythesizing it, by a cehmical process that begins by chlorinating propylene, which gives allyl chloride, which is oxidized with hypochlorite to dichlorohydrins, which reacts with a strong base to give epichlorohydrin. Epichlorohydrin is then hydrolyzed to give glycerol.
Is a chemical bond flexible or rigid?
Covalent bonds are "flexible", a bit like a spring, BUT the energy to make them vibrate is quantised and only specific frequencies (often in the infred spectrum) are "allowed"- this si the basis of IR and Raman vibrational spectroscopy.
Why polystyrene film is used for IR calibration?
the polystyrene film is cover all the ir range.
Why IR carbonyl stretching frequency for an amide is shifted to lower frequencies compared to the carbonyl base value?
The stretch frequency of a bond depends upon the constant force of the bond. In amides resonance structures, i.e. electron donating effect of the nitrogen, lower the force of the bond.
What are the IR frequencies of an aldehyde carbonyl group?
around 1700 cm^(-1)
What is the effect of hydrogen bonding on vibrational frequencies in case of IR spectroscopy?
Hydrogen bonding results in the broadening of the stretching frequencies of functional groups like -OH, -NH, -COOH etc.

What is the main principle of IR spectroscopy?
IR spectroscopy is useful in identifying functional groups in your sample. Many functional groups have specific absorption frequencies, so examination of IR spectra can tell you which functional groups are present (but not where they are structurally in your molecule). A table of common IR absorption frequencies are here: http://www.chem.ucla.edu/~webspectra/irtable.html Most of the time IR is used with NMR to identify a compound. IR can often be used independently to see if a reaction has worked (like if you are adding an azido group to your compound, you can use IR to see if your purified product has an azido absorption).

What is related to the frequency of a visible light wave?
Its apparent color as perceived by the human visual system. Lower frequencies look redder, while higher frequencies look more bluish or violet. As frequency goes down below the "visible" part of the spectrum, the light becomes "infra-red" or "IR", while higher frequencies above the visible spectrum are called "ultra-violet" or "UV".
What has the author L P Mendis written?
L. P. Mendis has written: 'Multicomponent polydiene-epichlorohydrin elastomeric systems'
Why can UV break apart molecules and IR only speeds up the molecules vibrations?
Ultraviolet waves have shorter wavelengths than Infrared waves. Since the relationship between wavelength and frequency is inversely proportional, UV waves have a much higher frequency than IR waves. IR waves have a frequency around 1012 Hertz, while UV waves' frequencies are around 1018 Hz. Thus, UV waves are more powerful than IR waves and can cause binds between molecules to break much more easily than IR waves.
How is infrared used in everyday life?
Much of the sun's heat is in infra red. The earth would be a frozen block if it were not for IR. More trivially, most tv remote controls work on infra red frequencies.
What does IR mean on my schedule It says I will be taking SPANISH IR. What does IR mean?
IR stands for: Introduction Remedial.
What is an IR Blaster?

What is the highest and shortest frequency waves?
There is no absolute limit on frequencies. The frequencies can be almost arbitrarily small or big.There is no absolute limit on frequencies.
