摘要

The M~+[cyclohexane][Ar](M = Li,Na,and K)cluster ions were investigated using infrared photodissociation spectroscopy in the C-H stretching region.The alkali metal cation binds to the cyclohexane ring above the ring on the S_6 axis via eta~3 coordination.The C-H stretching modes are perturbed due to binding of the metal cation and display a significant spread in frequency.The shifts are greatest for the Li~+ and decrease for Na~+ and K~+ with increasing ionic radius.It has been observed that cyclohexane displays greater selectivity for Li~+ over Na~+ than the cyclic ether,12-crown-4.The charge transfer interaction between Li~+ and cyclohexane is believed to be responsible for the selectivity of Li~+ over other alkali metal ions.
