Wotiz, John H. published the artcileThe infrared spectra of a number of isomeric normal acetylenic compounds, Product Details of C7H11Br, the publication is Journal of the American Chemical Society (1949), 3441-4, database is CAplus.

The infrared spectra of 28 normal acetylenic compounds and four substituted normal heptanes, C₅H₁₁CCH, C₄H₉CCCH₃, C₃H₇CC₂H₅, CH₆CC(CH₂)₄C, C₂H₅CC(CH₂)₃Cl, C₄H₉CCCH₂C, CH₃(CH₂)₆Br, HCC(CH₂)₅Br, CH₃CC(CH₂)₄Br, C₃H₇CC(CH₂)₂Br, C₄H₉CCCH₂Br, C₅H₁₁CCBr, CH₃(CH₂)₆OH, HCC(CH₂)₅OH, CH₃CC(CH₂)₄OH, C₂H₅CC(CH₂)₃OH, C₃H₇CC(CH₂)₂OH, C₄H₉CCCH₂OH, CH₃(CH₂)₆CN₂ HCC(CH₂)₅CN, CH₃CC(CH₂)₄CN, C₂H₅CC(CH₂)₃CN, C₃H₇CC(CH₂)₂CN, C₄H₉CCCH₂CN, C₅H₁₁CCCN, CH₃ (CH₂)₆CO₂CH₃, HCC(CH₂)₅CO₂CH₃, CH₃, C(CH₂)₄CO₂CH₃, C₂H₅CC(CH₂)₃CO₂CH₃, C₃H₇CC(CH₂)₂CO₂CH₃, C₄H₉CCCH₂CO₂CH₃, C₅H₁₁CCCO₂CH₃ are presented. The intensity of the CC band is observed to vary greatly. The band is most intense when the triple bond is near the end of the chain. If the triple bond is three or more positions from the end, the band is scarcely detectable.
