The high-resolution Fourier transform infrared spectrum of nitrogen trifluoride NF3has been studied in the v1+ v4perpendicular band region around 1523 cm−1. All experimental data have been refined applying various reduction forms of the effective rovibrational Hamiltonian developed for an isolated degenerate state of a symmetric top molecule. The v1= v4= 1 excited state of the14NF3oblate molecule was treated with models taking into account ℓ- andk-type intravibrational resonances. Parameters up to sixth order have been accurately determined and the unitary equivalence of the derived parameter sets in different reductions was demonstrated.

Diamagnetic Effect

One of the earliest applications of the Fermic-Dirac statistics was that of pauli to the treatment of the paramagnetism, due to the electron spin, of an electron gas. The result he obtained, for low temperatures, may be put in the form M p = 3/2 Nμ 2 H/ε 0 , where M p is the total magnetic moment due to the spin effect, N the number of electrons, μ the Bohr magneton, and ε 0 the maximum electron energy in the completely degenerate state. It was later shown by Landau that electrons, apart from the spin effect, gave a diamagnetic contribution to the susceptibility. The diamagnetic effect (which is zero on a classical basis) arises from the discreteness of the energy states of an electron in a magnetic field. For low temperatures the result obtained is M D = -½ Nμ 2 H/ε 0 , where M D is the diamagnetic contribution to the moment. The spin effect was further considered by Bloch, who gave, as a higher approximation at low temperatures, M P = 3/2 Nμ 2 H/ε 0 {1-π 2 /12( k T/ε 0 ) 2 }.

Usual Theory

The usual theory of g values cannot be applied to molecules as it is not gauge-invariant. Dirac’s wave equation is used to derive a gauge-invariant theory, and a general expression is obtained for the principal g values of a molecule in an orbitally non-degenerate state.
