'theoretical deduction' is correct and usable in written English.
It can be used when someone is attempting to draw a conclusion from a premise or set of assumptions. For example, "Through theoretical deduction we can conclude that the best course of action is to reduce costs."
Both theoretical deduction and experimental data indicated that the molecular design strategy was rational and efficacious.
These excellent optical performances are calculated by using FDTD numerical modeling and theoretical deduction.
Based on theoretical deduction and mathematical modeling, theoretical oscillation curves of phase difference were obtained.
The feasibility and performance of this proposed 6-DOF controller are validated by theoretical deduction and simulation results.
Ostwald makes this a purely theoretical deduction, but the practice of discarding first drops does not, I think, originate with him.
When the total fuel-travel-back time is minimized, so is the average refueling travel time of a random motorist, for which theoretical deduction is provided.
Both theoretical deductions and experimental trials have proved that the novel automatic vision-aided alignment system is robust and feasible for achieving precision to the nanometer scale.
The theoretical deductions show clearly that the basic sound generation mechanisms are associated with the vortex core deformation and the vorticity centroid dynamics, independent of the vortex system.
Challis was dubious, as he later wrote: "It was so novel a thing to undertake observations in reliance upon merely theoretical deductions; and that while much labour was certain, success appeared very doubtful".

Our theoretical deductions are consistent with both simulation and real data (Table 4).
