Types of molecules based on Moment of Inertia

The rotational properties of any molecule can be expressed in terms of the moments of inertia about three perpendicular axes set in the molecule. The moment of inertia of a molecule associated with an axis is defined as the sum of the product of mass of each atom multiplied by the square of its distance from the rotational axis through the center of mass of the molecule. Based on moment of inertia there are four types of molecules: linear molecules, symmetric top molecules, which are further subdivided into prolate symmetric top and oblate symmetric top molecules. Spherical top molecules and Asymmetric top molecules.

The example BF3 of oblate symmetric top molecule has a flaw. You drew the axes perpendicular to each other and it looks like the 2 Fluorine are along the axes. But in reality the angle between them are 120° not 90°

5:32 linear molecule
7:09 symmetric top molecules

[@ranakashif2700]

A rigid body where three axis are mutually perpendicular is called (a) symmetric top(b) antisymmetric top (c) spherical top(d) cylindrical top(e)all

Thanks, a lot, I want video on "relative population of rotational levels and Spectral intensity.

Nice video.. keep it up sir please

[@ChemWis]

Thank you, I will

[@dalalalbusaidi4148]

thanks alot this video is very helpful

[@ananthakrishnanb2158]

Video is nice . But 4 ads on 13 min video. Thats lil extra.

[@vengat3556]

in prolate looking that deformed sphere clearly I(a) is larger ,its contradicting

[@amarbarnwal7558]

I think he did mistake in oblate case, there should be Ib= Ic

[@beautyofchemistry7045]

NH3 is prolate

[@sudhaR2018]

Yes sir

[@bhavnamanhare1668]

Hindi me explain kriye
