What is the instrumental difference in IR and FTIR?
In FT-IR, an interferometer is used to collect a spectrum. This interferometer has a source, a beam splitter, two mirrors, a laser, and a detector. One part of the beam is transmitted to a moving mirror and the other is reflected to a fixed mirror. In Dispersive-IR, there is also a source and mirrors, but the source energy is sent though a sample and a reference path, through a chopper to moderate energy that goes to the detector, and directed to a diffraction grating. The diffraction grating separates light into separate wavelengths and each wavelength is measured individually.
Why astronomers use an interferometer?
Your eyes and brain form an interferometer, allowing for 3D imaging.
What is the source of FTIR instrument?
Don't know, but go on Wikipedia, it will tell you.
Why use KBr in FTIR?
The crystal has no visible peaks in the infrared spectrum making it transparent in ftir.
Why have you used non-electrolytic liquid in ultrasonic interferometer experiment?
if we know then why we use it

When several radio telescopes are wired together the resulting network is call?
Interferometer.

When was Plateau de Bure Interferometer created?
Plateau de Bure Interferometer was created in 1988.
What is the interferometer used for?
It allows two or more small telescopes to achieve the angular resolution of a much larger telescope. This instrument is credited to Albert A. Michaelson.
What is the purpose of compensating plate in michelson interferometer?
a compensating plate is used in michelson interferometer to compensate the additional path difference of ray 1
What did Albert Michelson do?
He is the inventorof the Michelson interferometer.
What is the source of FTIR instrument?
Don't know, but go on Wikipedia, it will tell you.
Range resolution of FTIR?
I always use 400 - 4000cm-1.
Why use KBr in FTIR?
The crystal has no visible peaks in the infrared spectrum making it transparent in ftir.
Where is a carbonyl group detected by FTIR?
At around 1700-1800 [1/cm]
Why NaCl is not used in FTIR?
It is used but not after wavelengths higher than 15 micrometres.
