Notes. (a)The product of the parameter and operator from a given row yields the term used in the torsion-rotation-tunneling Hamiltonian, except for F, ρ, and A, which occur in the Hamiltonian in the form , where γ in these operators is shorthand for γ/ 〈R|γ|R〉 and so its matrix elements give only a ± sign to the final matrix element of the full operator expression (see Kleiner & Hougen (2015)). Operators of species B1 in G12 (such as cos3α) are not allowed in the Hamiltonian. Such operators can be made A1 in G12 by multiplying them by the wagging coordinate γ (which is also B1 in G12). (b)All parameters are given in cm−1 except for RHORHO, which is unitless. The parameter value given in square parentheses (such as F and V9) was fixed in our final fit at a value taken from an earlier fit where it was floated. (c)The symbols t and r give the order of the torsional part and the rotational part of the operator, as defined in (Kleiner & Hougen 2015); w gives the wagging order, n = t + r + w gives the total order of the operator. (d)The column contains the operator used in the hybrid Hamiltonian multiplied by the parameter adjusted in the least-square fit. (e)This column contains the value of the parameter determined in the fit, with one standard uncertainty in units of the last digits given in parentheses. (f)Value fixed in the fit. (g)This parameter was erroneously named FWAGBC in the previous paper (Kleiner & Hougen 2020).
