The Journal of Physical Chemistry, A and

The leadership of U.S. physical chemists is also demonstrated by their strong overall contributions to the Journal of Physical Chemistry A and B (about 35 percent of all papers and an average of 75 percent of the 20 most accessed papers from 2004 to 2005). In these two journals, international physical chemists have increased their contributions in the past five years from 57 to 65 percent. The most active countries were Japan, China, Spain, Germany, Italy, France, the United Kingdom, Sweden, Belgium, India, and Canada. Additionally, strong U.S. leadership in physical chemistry is apparent by the 40 percent rate for U.S. contributions of papers to the Journal of Chemical Physics. 

U.S. scientists were responsible for authoring 51.5 percent of highly cited physical and computational chemistry articles in 1990-1994, 47.3 percent in 1995-1999, and 49.8 percent from 2000 to 2006. Of the top hot papers, physical chemistry is the fourth most popular area of chemistry, accounting for 12.2 percent of the top hot papers from 2004 to 2006. The United States and Western Europe are responsible for most of the hot papers, contributing 50 percent and 43.8 percent, respectively. The Journal of Physical Chemistry A and B contained some of the most accessed ACS articles, with 65 percent (Part A) and 75 percent (Part B) of the articles coming from the United States. 

The Institute for Scientific Information database was interrogated to determine the number of incidences of the string MP2 in titles and keywords in four specific primary research journals during 2000. The journals chosen were The Journal of Chemical Physics, Chemical Physics Letters, The Journal of Physical Chemistry A and The Journal of Physical Chemistry B. We describe the results obtained for each of these journals in turn.
