My thesis problem and my solution for it required my major professor to pass it on to someone who knew more about the subject than he did. It wasn't Luibrand.
To solve the problem I used a trick learned by other chemical kineticists called the method of Gould and what was for the time the most sophisticated hand held calculator of the time, 1974, a HP-97 or HP-98 and several days of punching numbers into it.
This led to an inspiration as to the nature of the molecular events in the reaction pot.
A mechanism was developed. From the mechanism a set of differential equations were written and solved.
I gained access to a WANG 720-C in the UCD Botany Department and wrote a 1200 line program in assembler to process the physical data from the kinbetic experiment.
All the symbols of the language were written on the faces of the keys on the keypad which was about the size of a large typewriter. Tape drive for data storage.
