Vibrational modes and tip enhanced Raman spectroscopy (TERS) of a new carbon allotrope, cyclo[18]carbon (C18), were studied by density functional theory. A silver cluster tip was used to probe the interaction with C18, which is dependent on the distance and the atomically resolved positions. The TERS images show the position of the C[triple bond, length as m-dash]C bonds, as observed in a recent experimental report.
通过密度泛函理论研究了新型碳同素异形体环[18]碳（C18）的振动模式和尖端增强拉曼光谱（TERS）。使用银团簇尖端来探测与 C18 的相互作用，这种相互作用取决于距离和原子分辨位置。TERS 图像显示了 C[三重键，长度为破折号]C 键的位置，这与最近的实验报告中观察到的一致。
