Abstract
The search for other superconductors in the MgB 2 class currently is focussed on Li 1− x BC, which when hole-doped (concentration x) should be a metal with the potential to be a better superconductor than MgB 2. Here we present the calculated phonon spectrum of the parent semiconductor LiBC. The calculated Raman-active modes are in excellent agreement with a recent observation, and comparison of calculated IR-active modes with a recent report provides a prediction of the LO–TO splitting for these four modes, which is small for the B–C bond stretching mode at ∼1200 cm −1 , but large for clearly resolved modes at 540 and 620 cm −1 .
