EI spectra of 2,4-octadiyne-1-ol (MW=120) shows prominent peaks =
at 66, 77, 91 (also 105, 107, 122) and 183, 310 (probably collision =
peaks). Homologous compounds give similar spectra.

     I would be grateful if someone with experience in MS spectra =
interpretation could help me explain the fragmentations/reactions =
leading to the 66, 77, 91, 183 and 310 peaks.
      Any hint appreciated !

      Thank you in advance !
