✦ Synopsis

Irregularities of the Moon's rotation due to rotation of the ecliptical plane were derived for all three libration components. Optimum values of coefficients in the linearized equations of motion, which strongly affect the magnitude of the resulting terms, were determined by comparing the rotation relative to the moving and to the fixed reference ecliptical system. Ecliptic rotation causes monthly oscillations of the Moon's polar axis of 6.1" and deviations of 0.3 U from uniform rotation along that axis with a period of 18.6 yr.

An analytical expression is derived to estimate how much parent rotational energy is carried over to the fragment rotation when a molecule is dissociated. The model is based on the classical treatment of rotational motion, by which the effect can be estimated separately from other sources of rotatio
