Resumen
En el presente trabajo se han aplicado técnicas de Modelización Molecular y Química Computacional al campo de la Astroquímica. Se ha llevado acabo el estudio de las estructuras molecular y electrónica de las moléculas C2H2N y C2H2N+ que han sido detectadas en el medio interestelar. Para ello se ha empleado el programa informático Gaussian 16W, aplicando la teoría del Funcional de la Densidad (DFT), utilizando cuatro tipos de funcionales (B3LYP, M06-2X, MN15 y ωB97X-D) y dos conjuntos de bases (6-31+G** y 6-311+G**).
En este trabajo se han obtenido datos de sus propiedades estructurales y moleculares (longitud y ángulos de enlace, momento dipolar, polarizabilidad, etc.) y datos espectroscópicos rotacionales y vibracionales con sus respectivos espectros infrarrojos. Los cálculos teóricos se han llevado a cabo dentro de la aproximación de molécula aislada, rotor rígido y oscilador armónico.

In this work, data have been obtained on their structural and molecular properties (bond length and angles, dipole moment, polarizability, etc.) and rotational and vibrational spectroscopic data with their designated infrared spectra. Theoretical calculations have been carried out within the isolated molecule, rigid rotor and harmonic oscillator approach
