The 9th Congress on Electronic Structure: Principles and Applications (ESPA), will be held in Badajoz (Extremadura, Spain) from the 2nd to the 4th of July 2014.

The ESPA conferences, initiated in 1998, have been held every two years and cover all major fields of Theoretical and Computational Chemistry. The previous ESPA editions were organized in Madrid (1998), San Sebastián (2000), Sevilla (2002), Valladolid (2004), Santiago de Compostela (2006), Palma de Mallorca (2008), Oviedo (2010) and Barcelona (2012). These conferences were initially intended to bring together the Spanish Theoretical and Computational Chemistry community. They have grown over time (both in national and international participation), thereby evolving into a key event with international reputation in the field.

The conference encompasses plenary lectures, oral communications and posters presentations. All participants are invited to submit an abstract for an oral communication or a poster.

Proceedings of the conference will be published in Theoretical Chemistry Accounts upon the usual peer-review process. Details on how to submit the manuscript to the journal will be conveniently provided.

We hope to meet you in Badajoz between the 2nd and the 4th of July 2014.

Previous to the ESPA2014 the Third Annual Workshop of the Joint Doctorate Program on Theoretical Chemistry and Computational Modelling (TCCM) (http://www.emtccm.org/tccm-jd/) will take place the 1st of July in the Faculty of Sciences, Universidad de Extremadura.
