STUDY ON THE ELECTRONIC STRUCTURE OF THE COMPLEX OF LANTHANUM CHLORIDE WITH 15-CROWN-5

I. INTRODUCTION In a previous paper we reported the electronic structure of La（NO3）3·15-crown-5, indicating that the molecular structure with three nitrate groups on one side of the 15-crown-5 ring, that is, the umbrella-shaped configuration, has minimum total energy.It is expected that a further study on the correlation between the molecular
