You can view incident IR radiation as an oscillating electric field ( the 'wave-like' view of EM radiation.) As such, it effects the vibration of a molecule by inducing a dipole oscillation of the same frequency. The connection is most clearly seen if you consider that the induced dipole oscillation produces an identical oscillating electric field to the field that induced it. A molecule can only produce an oscillating electric field by vibration if its vibration produces a change in dipole moment (a non-polar molecule would produce a constant electric field regardless of the vibration.) I hope that helps

What happens when water absorbs an IR photon?
When water absorbs an infrared (IR) photon, the molecular vibrations of the water molecules increase as they absorb the energy from the photon. This increase in vibrational energy causes the water molecules to move more vigorously and increase in temperature.
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 do dipole dipole forces do?
Hold polar molecules together
How do polar and non-polar bonds interact with each other?
Polar molecules reacts with polar molecules and non-polar molecules react with non-polar molecules.

Is toluene or hexane hygroscopic?
Neither toluene nor hexane are hygroscopic, as they do not readily absorb or attract water from the atmosphere. They are both non-polar solvents and typically do not form strong interactions with water molecules.
Explain glass cell cannot be used for IR region?
Glass absorb IR.
Why do oil and water hate each other?
Water is polar while oils are non-polar. Molecules that are polar will mix with other polar molecules, and non-polar molecules will mix with other non-polar molecules. Polar and non-polar molecules will not mix.

how do you explain what polar molecules are?
Water molecules are polar molecules. Both of the bonds inside the molecule are polar bonds.
Are sugars non polar Molecules?
No, sugars are polar molecules considering that they will interact and dissolve in water (which is also a polar molecule). Polar molecules will only interact with other polar molecules and vice-versa.
How do polar and non-polar bonds interact with each other?
Polar molecules reacts with polar molecules and non-polar molecules react with non-polar molecules.
Are non-polar molecules more attracted to other non-polar molecules or polar molecules?
Non-polar molecules are generally more attracted to other non-polar molecules due to the similar distribution of electronic charge. This attraction is known as London dispersion forces. Polar molecules tend to interact with other polar molecules through stronger dipole-dipole interactions or hydrogen bonding.
Are hexane molecules polar?
No, hexane molecules are non-polar.
