Calculations are presented of the frequencies and the probabilities of the lowest vibrational transitions of the H2(+) molecular ion in strong magnetic fields approximately equal to 10 to the 12th to 10 to the 13th gauss. The wavelengths corresponding to these fields are approximately 270-4500 A. The potential energy curves U(R) for the H2(+) ion in these strong magnetic fields are determined using the variational method. Only the case where the internuclear axis is parallel to the magnetic field is considered. It is found that the transition frequency and probability both increase relatively rapidly with the magnetic field strength. It is suggested that this fact can serve as a basis for developing a method of measuring the magnetic field near the surface of a neutron star if appropriate spectral lines are detected.
