Vibrational / rotational contributions<br />
Many measurements are at λ = 1064 nm. For <strong>org</strong>anic molecules, typically:<br />
- above vibrational frequencies, so can neglect vibrations<br />
- below electronic resonances so little dispersion<br />
Rotational and vibrational contributions can be estimated from simple<br />
harmonic models, for low-frequency response (e.g. THz).<br />
Z* = Born effective charge<br />
