“…Various different conventions are used in the literature concerning the sign of the g-factor [43]. Here, we define the sign of the g-factor such that γ > 0 for g > 0 and γ < 0 for g < 0.…”

“…(1) the rate of change of the magnetic moment is therefore parallel to the torque for positive g and antiparallel to the torque for negative g. While we are interested in this work in the spectroscopic g-factor, and hence in the relation between the rate of change of the magnetic moment and the torque, Ref. [43] discusses the relation between the magnetic moment m and the angular momentum L that generates it, i.e., m = γ static L. Since differentiation with respect to time and use of T = dL/dt leads to Eq. ( 1) our definition of the signs of g and γ agrees essentially with the one suggested in Ref.…”

We investigate Gilbert damping, spectroscopic gyromagnetic ratio and current-induced torques in the one-dimensional Rashba model with an additional noncollinear magnetic exchange field. We find that the Gilbert damping differs between left-handed and right-handed Néel-type magnetic domain walls due to the combination of spatial inversion asymmetry and spin-orbit interaction (SOI), consistent with recent experimental observations of chiral damping. Additionally, we find that also the spectroscopic g factor differs between left-handed and right-handed Néel-type domain walls, which we call chiral gyromagnetism. We also investigate the gyromagnetic ratio in the Rashba model with collinear magnetization, where we find that scattering corrections to the g factor vanish for zero SOI, become important for finite spin-orbit coupling, and tend to stabilize the gyromagnetic ratio close to its nonrelativistic value.

“…The convention used here follows (iii) Brown et al (2000) with a negative g e (see Chapter 6 and Mohr et al 2008). Further different sign conventions for the electronic g-factor are discussed in Brown et al (2000). Historically, g e was defined positive (g e > 0), e is the (positive) elementary charge, therefore γ e < 0 and a minus sign would have to be introduced in the equation for γ e given here.…”

“…A convention for the g-factor has been proposed, in which the sign of g is positive when the dipole moment is parallel to its angular momentum and negative when it is antiparallel. Such a choice would require the g-factors for the electron orbital and spin angular momenta to be negative (Brown et al 2000) (see Section 3.3, Note 10). (18) The observing (B 1 ) and irradiating (B 2 ) radiofrequency flux densities are associated with frequencies ν 1 , ν 2 and with nutation angular frequencies Ω 1 , Ω 2 (around B 1 , B 2 , respectively).…”

A summary of conventions, symbols, quantities, units, and constants which are important for high-resolution molecular spectroscopy is provided. In particular, great care is taken to provide definitions which are consistent with the recommendations of the IUPAC "Green Book", from which large parts of this article are drawn. While the recommendations in general refer to the SI (Système International), the relation to other systems and recommendations, which are frequently used in spectroscopy, for instance atomic units, is also provided. A brief discussion of quantity calculus is provided as well as an up-to-date set of fundamental constants and conversion factors together with a discussion of conventions used in reporting uncertainty of experimentally derived quantities. The article thus should provide an ideal compendium of many quantities of practical importance in high-resolution spectroscopy.

The basic ideas involved in the application of model Hamiltonians involving angular momentum operators to predict energy levels and transition intensities of various molecular systems are introduced. Such methods are essential for understanding many molecular systems, and are illustrated here with a few selected examples. These include two interacting nuclear spins, “forbidden” singlet–triplet transitions and the energy‐level patterns associated with Hund's cases (a)–(c) in a diatomic molecule.
