Abstract
Using the LGP--30 Digital Computor, a subroutine has been developed for the solution of secular determinants of order 2 through 32. The subroutine is available in printed form or on punched tape. The method of successive approximations is used. The program is so arranged that it is unnecessary to store any intermediate numbers at a higher numbers of significant figures than those of the data put into the program. Application to the vibrational frequencies of the formamide molecule is given.
