WebJan 30, 2024 · The number of vibrational normal modes can be determined for any molecule from the formula given above. For a diatomic molecule, N = 2 so the number of modes is 3 × 2 − 5 = 1. For a triatomic linear molecule (CO 2 ), it is 3 × 3 − 5 = 4 and triatomic nonlinear molecule (H 2 O), it is 3 × 3 − 6 = 3 and so on. WebApr 5, 2024 · The high value of the dielectric constant means the value of capacitance can be maximised. It can be seen from the capacitance formula in the parallel plate capacitor: C = Kϵ0 A/d. where K refers to the dielectric constant. C refers to the capacitance of a parallel plate capacitor. A refers to the area of parallel conducting plates.
