We report a set of experimental observations on electromagnetically induced transparency in acetylene filled hollow-core photonic crystal fiber, involving both Λ-type and V-type interactions over several lines of the R-branch of the ν1 + ν3 ro-vibrational overtone band. Transparency as high as ~70% was achieved. A theoretical account of the sources of decoherence shows that collisions with the inner wall of the fiber core and laser frequency-jitter dominate the coherence decay.
