Identification of Lewis basic sites can be done using several techniques:
1. Spectroscopic Methods: FTIR, NMR, and EPR spectroscopies can be used to identify the presence of electron-donating groups. 2. Computational Chemistry: Density Functional Theory (DFT) calculations can predict the location and strength of Lewis basic sites. 3. Experimentation: Reactivity tests involving known Lewis acids can provide indirect evidence of the presence and strength of Lewis basic sites.
