Un modelo simple basado en la aproximación adiabática, se ha implementado para estudiar el espectro energético de una molécula de hidrógeno confinada en un anillo cuántico muy estrecho. El sistema completo se encuentra bajo la influencia de campos externos: magnético y de presión hidrostática. Los resultados muestran la posibilidad de obtener moléculas artificiales cuyos parámetros característicos: longitud de equilibrio, energía de disociación y punto de retorno, pueden ser seleccionadas de antemano al cambiar los factores geométricos del anillo y las intensidades de los campos externos, hecho que contrasta con los valores que registra los valores inmodificables que impone la naturaleza a la molécula natural de hidrógeno.
