Research on the behavior of the atoms and molecules in extremely strong magnetic fields became a new focus of theoretical study after the astrophysical discovery of white dwarf stars (106-109 G) and neutron stars (1011-1013 G) in the 1970s.[1] Relevant works have shown that the partial spectrums can be labeled by theoretical calculation.In 2002,the new unidentified spectrum of neutron star 1E1207.4-5209,which was observed by the Chandra x-ray observatory,aroused the further interest of theorists on the behavior of molecules in strong fields.[2] More new features occur in molecule-field systems than in atom-field systems.For example,even for the simplest H2+,some unbound states without field can become bound states in strong fields.[3] Some states of H2+ in parallel magnetic fields may not exist when the angle between the magnetic field direction and molecular axis changes.[4]Moreover,new chemical compounds,such as exotic ions H32+,H32+[5,6] and the hydrogen molecule chain HN,[7] may occur in strong fields.
