What are IR-active and inactive molecules?
In order for a molecule to be IR active, the vibration must produce an oscillating dipole. This usually means that the bond (or bonds) in question have are polar to begin with so that they have a dipole. Therefore symmetrical molecules like O2 and N2 are not IR active, but molecules like H2O with polar bonds are IR active.
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.
Transparent material for IR?

Other materials, such as germanium and zinc selenide, are also widely used for IR applications due to their transparency in the IR spectrum.

Why do peaks in IR are negative?
In infrared (IR) spectroscopy, peaks appear negative due to the way the instrument measures absorbance. The IR spectrum is typically plotted as transmittance (percentage of light transmitted) versus wavenumber or frequency. When a sample absorbs IR radiation, less light reaches the detector, resulting in a decrease in transmittance, which is reflected as a negative peak on the spectrum. Essentially, the negative peaks indicate specific frequencies at which the sample has absorbed energy.
