This paper investigates the anisotropy of the adiabatic relaxation time (T (2)(omega), omega -> a, where omega is the Larmor frequency) of adsorbed monolayer solid He-3. We calculate based on the phenomenological Heisenberg Hamiltonian with the nearest-neighbor and the next nearest-neighbor exchange interactions. Furthermore, the four particle exchange in the triangular plane is also incorporated. To calculate , it is necessary to compute the second and the fourth moments of the resonance line and . To obtain them, we can use the formulas published in previous studies. From the results, we can observe no significant difference between the nearest-neighbor Heisenberg model and the four particle spin interaction models. A comparison of the present results and the experimental data is briefly discussed.
