Popis:	Resonance Raman spectra of hydrogen-capped linear carbon molecules, polyynes H(–C C–)nH (n = 5,6), were measured in n-hexane. For C10H2, the peaks at 2123 cm−1 and 2017 cm−1 were identified as the ν3(σg) and ν4(σg) modes in D∞h symmetry, respectively. For C12H2, the peaks of ν3(σg) at 2097 cm−1 and ν4 (σg) at 2053 cm−1 were identified. The relative intensities of the first-order Stokes lines and their resonance enhancement are discussed in terms of the Franck–Condon overlap and resonance absorption relevant to the fully-allowed electronic transition of 1 Σ u + ↔ X ∼ 1 Σ g + .
