We define a new parameter 𝐼 π‘˜ , 𝑛 involving quotient of Ramanujan's function πœ’ ( π‘ž ) for positive real numbers π‘˜ and 𝑛 and study its several properties. We prove some general theorems for the explicit evaluations of the parameter 𝐼 π‘˜ , 𝑛 and find many explicit values. Some values of 𝐼 π‘˜ , 𝑛 are then used to find some new and known values of Ramanujan's class invariant 𝐺 𝑛 .
