The circuit looks similar to this. I am going to do it by hand to find Va and Vb but would like to use a solver or program to make sure I got the right values.
Use Xc = 1 / jωC and Xl = jωL. Pick a frequency for ω and solve for C and L using the specified reactances on your diagram. Plug the values into the LTSpice program.
