摘要：
We report the infrared reflectance of the 10.4 K organic superconductor kappa-(ET)(2)Cu(SCN)(2) as a function of applied magnetic field at 4.2 K, allowing us to explore changes in intramolecular vibrational modes between the superconducting (low field) and normal (high field) states. Several vibrational modes display field dependence, including nu(3) (A(g)), nu(60) (B-3g), and nu(21) (B-1g). Changes in nu(3), which involve the central C=C bond of the ET building block molecule, are especially complex, and include frequency, linewidth, and intensity modifications. These results show that intramolecular vibrational modes are involved in the superconducting to normal state transition in kappa-(ET)(2)Cu(SCN)(2) below T-c.
