• parameter; linear carbon chains; Raman spectroscopy; Introduction Phonons, their mutual interactions (ph–ph interactions), and their interactions with electrons (e–ph interactions) play fundamental roles in how materials respond to electric (e.g., difference of potentials), thermal (e.g., temperature

Linear carbon chains (LCC) are 1D systems that are classified into two categories: polyynes (displaying alternating triple and single bonds between constituent carbon atoms

Indeed, many works [29][30][31][32][33][34][35] have offered a detailed theoretical interpretation of the relation
