The work, carried out by researchers at the National Institute of Optics of the National Research Council (CNR-INO), at the European Laboratory for Nonlinear Spectroscopy (LENS), will be presented in the journal Physical Review Letters. This research shows the lowest concentration ever measured with laser spectroscopy techniques, a gas of molecules, demonstrating that it is possible to detect carbon dioxide at pressures over a million billion times lower than the atmospheric pressure.<\/p>\n<p>Visit the explicative <a href=\"http:\/\/prl.aps.org\/abstract\/PRL\/v107\/i27\/e270802\">Web page<\/a><\/p>\n<p>News by Baldanzi Elisabetta<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Molecular gas sensing below parts per trillion: Radiocarbon-dioxide optical detection<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[],"tags":[],"class_list":["post-7475","post","type-post","status-publish","format-standard","hentry"],"_links":{"self":[{"href":"https:\/\/www.ino.cnr.it\/index.php?rest_route=\/wp\/v2\/posts\/7475","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.ino.cnr.it\/index.php?rest_route=\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.ino.cnr.it\/index.php?rest_route=\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.ino.cnr.it\/index.php?rest_route=\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.ino.cnr.it\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=7475"}],"version-history":[{"count":0,"href":"https:\/\/www.ino.cnr.it\/index.php?rest_route=\/wp\/v2\/posts\/7475\/revisions"}],"wp:attachment":[{"href":"https:\/\/www.ino.cnr.it\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=7475"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.ino.cnr.it\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=7475"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.ino.cnr.it\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=7475"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
