Name: Dept: Date: 2018 Annual Survey of Biological and Chemical Agents regulated by Homeland Security (and carcinogens regulated by OSHA) Due (date) All labs that do not have a current chemical inventory in Chematix MUST complete this survey. The University is required to make an annual report of all chemicals on the Chemical Facility Anti-Terrorism Standards (CFATS) lists. Additional information regarding the regulations is available on the EH&S website at http://www.safety.rochester.edu/restricted/occsafe/chemicalagent.html and https://www.selectagents.gov. 1. Please review the lists on the following pages and indicate if any are possessed by your lab. The CAS# has been added to the list for ease of searching databases. The CAS# is a Chemical Abstract Service numbering system which assigns a unique number to every chemical substance based on structure; this helps avoid confusion by use of synonyms or different naming conventions. a. If yes for possession, place an X in the applicable box and if requested, include the quantity held in your lab. b. If no, leave blank. 2.

Ghosh Department of Chemistry, University of Kalyani, Kalyani-741235, India Email: [email protected], Fax: +91-33 25828282 Received: 2 July 2006 / Accepted: 24 July 2006 / Published: 25 August 2006 Abstract: In order to understand the structure-property relationship, SPR, an energy- partitioning quest for the origin of the barrier to the internal rotation of two iso-structural molecules, hydrogen peroxide, H 2O2, and fluorine peroxide, F 2O2 is performed. The hydrogen peroxide is an important bio-oxidative compound generated in the body cells to fight infections and is an essential ingredient of our immune system. The fluorine peroxide is its analogue. We have tried to discern the interactions and energetic effects that entail the nonplanar skew conformation as the equilibrium shape of the molecules. The physical process of the dynamics of internal rotation initiates the isomerization reaction and generates infinite number of conformations. The decomposed energy components faithfully display the physical process of skewing and eclipsing as a function of torsional angles and hence are good descriptors of the process of isomerization reaction of hydrogen peroxide (H 2O2) and dioxygen difluoride (F 2O2) associated with the dynamics of internal rotation. It is observed that the one-center, two-center bonded and nonbonded interaction terms are sharply divided in two groups. One group of interactions hinders the skewing and favours planar cis/trans forms while the other group favours skewing and prefers the gauche conformation of the molecule. -
