Experimental study of the reaction of C3N anions with acetylene (C2H2) at various energies

J. Heyrovsky Institute of Physical Chemistry of the ASCR, v. v. i., Prague (Czech Republic)

Host institution: Centre Universitaire Paris-Sud, Paris(FR)

 

Subject of this short term scientific mission was experimental study of the reaction of C3N- ions with neutral acetylene molecules:

C3N- + C2H2 → CN- + C5H2         (1a),

C2H- + HC3N      (1b),

C5N- + H2          (1c).

This reaction is important due to its potential relevance to the chemistry of cold interstellar clouds and its abundance in the atmosphere of Saturn’s moon Titan.

The CERISES apparatus that is a disposition is the laboratory of Christian Alcaraz at Centre Universitaire Paris-Sud was used for this project. As a part of STSM, experimental facilities were modified for reactions with negative ions.

The absolute cross-section value of C2H- ions formation in the of range collision energy 0.1 – 20 eV was measured. Results for production of C2N- ions (equation 1b) obtained during this short term scientific mission are in a good agreement with previous (relative) experimental data measured in the laboratory in Prague.

Short Term Scientific Missions (STSMs)

Aiming at fostering collaboration, sharing new techniques, and infrastructure that may not be available in other participants' institutions or laboratories. STSMs are intended especially for young PhD researchers, but they are open to senior researchers as well. View the documents at this link.

 It should be explicitely noted that Master students are not eligible for STSMs which are for PhD students and more experienced researchers.

The life-Origins COST Project


Life-ORIGINS (TD1308) is a Trans Domain European COST Action dedicated to the scientific investigation of the origins and evolution of life on Earth and habitability of other planets.

The Action has specifically excluded the search for intelligent extraterrestrial life in its portfolio. Creationist theorems are also outside the Action’s remit.

Individuals are not allowed to use the name of the Action, its logo or any corporate identity of COST TD1308 in any communication without prior approval of the Management Committee.

All publications referencing the support of the Action should be sent to the appropriate Working Group chair at the time of submission.
