The impact of computers on atomic physics

Title of program: SOUND ABSORPTION Catalogue Id: ABSA_v1_0 Nature of problem Sound absorption measurements in polyatomic gases contain information about the energetically inelastic collisions which take place in the gas, i.e., those collisions in which the rotational state of one or both of the molecules changes. This fact manifests itself through the so-called bulk or volume viscosity. It is the purpose of this communication to describe a method whereby a reduced bulk viscosity may be obtained from the sound absorption data directly. Versions of this program held in the CPC repository in Mendeley Data ABSA_v1_0; SOUND ABSORPTION; 10.1016/0010-4655(72)90110-5 This program has been imported from the CPC Program Library held at Queen's University Belfast (1969-2018)程序名称：吸声（SOUND ABSORPTION） 目录编号：ABSA_v1_0 问题本质：多原子气体的吸声测量数据蕴含气体内部发生的能量非弹性碰撞信息，即引发单个或两个分子转动状态发生改变的碰撞。该类碰撞的效应可通过所谓的体积黏度（bulk or volume viscosity）体现。本文旨在介绍一种可直接从吸声数据中获取约化体积黏度的方法。 本程序在Mendeley Data的CPC库中的存档版本为：ABSA_v1_0; SOUND ABSORPTION; 10.1016/0010-4655(72)90110-5 本程序源自贝尔法斯特女王大学维护的CPC程序库（1969-2018）
