首次在液相中观察到拉曼回波。乙腈的对称甲基伸缩被均匀加宽，在时间分辨相干拉曼散射实验和最近的理论不一致，但在协议与线形研究和计算机模拟。振动主要与快速的碰撞溶剂运动相互作用，而不是与长寿命的结构特征相互作用
Raman echoes are observed for the first time in the liquid phase. The symmetric methyl stretch of acetonitrile is shown to be homogeneously broadened, in disagreement with time-resolved coherent Raman scattering experiments and recent theory, but in agreement with line-shape studies and computer simulations. The vibration interacts primarily with rapid, collisional solvent motions, not with long-lived structural features
