Structural, Electronic, and Vibrational Properties of Amino-adamantane and Rimantadine Isomers

We performed a first principles total energy investigation on the structural, electronic, and vibrational propel ties of adamantane molecules, functionalized with amine and ethanamine groups. We computed the vibrational signatures of amantadine and rimanadine isomers with the functional groups bonded to clinic:ill carbon sites By comparing Out results with recent infrared and Raman spectroscopic data, we discuss the possible presence of different isomers in experimental samples.
