Lets look at the molecule 2-butyne. H3C-C=C-CH3. Notice this molecule is symmetrical about a triple bond.
The C-C triple bond in 2-butyne is IR inactive because of the molecule's overall symmetry. For 1-butyne, you would expect to see a weak peak from 2100-2250 (indicative of a C-C triple bond), but you would not expect to see the same for 2-butyne.

How do you distingish strecched vibration in ir spectra?
i think in ir spectra the vibrations are common but what is the diffrerance between strecched and vibrational
Why polystyrene film is used for IR calibration?
the polystyrene film is cover all the ir range.
Is chcl3 ir active?
yes and it should have 9 IR active vibrations
Oxy IR how long does it stay in your system?
oxy ir 30 how long in your system
What is carbonyl index?
ration between absorption intensities of C=O and CH2.Its a kind of expression to talk about hydrophillicity of polymers.Minly concerned with FT-IR spectrum
What is difference between IR and FT IR?
nothing
What is the maximum distance reached using IR transmission?
Between 2 standard IR devices it is 1 meter. Between 2 low power IR devices it is 0.3 meter Between a standard and a low power IR device it is 0.2 meter
What is the difference between IR and FT IR instruments?
A standard IR runs a single spectrum. An FT-IR uses an interferometer and makes several scans and then uses Fourier Transforms to convert the interferogram into an infrared spectrum.

What is the difference between NAIR and FT-IR instruments?
nothing
What is the difference between pir movement sensor and ir sensor?
Passive simply means that the unit does not emit IR light, but does detect it. All warm things emit some degree of IR. a PIR motion detector senses the difference between a warm body and the cold background. Active IR emits IR light to illuminate an area to be "seen" with it's CCD that is sensitive to IR. Most new Sony camcorders use active IR for "night vision". IR alone, with no modifier, simply refers to the spectrum of light known as Infra Red, which is slightly above human's vision range.
What is the frequency of IR spectrum?
Between O.7 and 300 micrometres
What is it called ir you grow hair in between your two eyebrows?
Monobrow or a Unibrow:)
What is difference between Hipot and IR test?
With Hipod leakage current of any circuit (HT Distribution/ Transmission Lines) can be determine and with IR Test insulation resistance between two circuit or parts of machine is determined.
IS there a difference between Oxycontin hcl 5mg and oxycodone ir 5mg?
Yes Oxycontin hydrochloride is a time released tablet and oxycodone ir is an instant release tablet.
What is an IR cable for a TV box?
An IR Blaster cable is a USB device. It creates a wireless, infrared connection between your cable box and the PC running beyond TV.
