We have characterized the structures of Snn cations up to n568 using ion mobility measurements. Up to n;35, tin clusters track the prolate growth pattern previously found for Sin and Gen . However, the detailed size-dependent variations start deviating from those observed for Sin above n514 and Gen above n521. Over the n;35– 65 size range, tin clusters gradually rearrange towards near-spherical...

If the most perplexing thing in the world is a lack of theory, the second most perplexing must be an abundance of it. This contribution clarifies the notion of pluralism by introducing an often neglected but crucial distinction between different levels at which pluralism can be situated. It intends to provide a framework for scholars dealing with the question how to manage the divergence of vie...
