Hi,

Determine the equivalent capacitance between points a and b of below circuit:

You can calculate the impedance using AC analysis and derive the capacitance from the imaginary part. This assumes the use of Rs-Cs model. You can easily modify this for your specific circuit. You can either remove the GND reference and relocate it to node b, or change the .func Z() to be fed with a differentiated voltage. Just be caution the ground.
