B , Just Accepted Manuscript • DOI: 10.1021/jp300005g • Publication Date (Web): 12 Mar 2012 Downloaded from http://pubs.acs.org on March 13, 2012 Just Accepted “Just Accepted” manuscripts have been peer-reviewed and accepted for publication. They are posted online prior to technical editing, formatting for publication and author proofing. The American Chemical Society provides “Just Accepted” as a free service to the research community to expedite the dissemination of scientific material as soon as possible after acceptance. “Just Accepted” manuscripts appear in full in PDF format accompanied by an HTML abstract. “Just Accepted” manuscripts have been fully peer reviewed, but should not be considered the official version of record. They are accessible to all readers and citable by the Digital Object Identifier (DOI®). “Just Accepted” is an optional service offered to authors. Therefore, the “Just Accepted” Web site may not include all articles that will be published in the journal. After a manuscript is technically edited and formatted, it will be removed from the “Just Accepted” Web site and published as an ASAP article. Note that technical editing may introduce minor changes to the manuscript text and/or graphics which could affect content, and all legal disclaimers and ethical guidelines that apply to the journal pertain.

Fax: (734)647-1604 Abstract The morphology of icosahedral viruses range from highly spherical to highly faceted, and for some viruses a shape transition occurs during the viral life cycle. This phenomena is predicted from con- tinuum elasticity, via the buckling transition the- ory by Nelson ( Phys Rev E 2003, 68, 051910), in which the shape is dependent on the Foppl- von K´arm´an number ( γ ), which is a ratio of the 2-dimensional Young’s modulus ( Y ) and the bend- ing modulus ( κ ). However, until now, no direct calculations have been performed on atomic level capsid structures to test the predictions of the the-...
