There is a large emphisis on fucntialising materials to create magnetic and electrical materials. Tetracyanoquinodimethane is a famous material discovered in the 1960 and ws quickly identified as a having novel optical proeprties and being a powerful electron acceptor. In this study we want to study how the electron is distrobuted across a TCNQ molecule when different numbers of flourine are added to the quinodial ring using muon spin resoance. This will provide us with an experimental way of confirming how one could tune materials to shift transition temepratures or change the electrical properties.
