Abstracts of scientific articles offer the first contact their readers have with the issues and results presented by the article, thus having a pivotal screening role. Due to their importance, they need to be well written, taking into account their genre-specific rules. Several studies have aimed at describing its particular textual structure, its rubric, though there is still much data to be amassed. The purpose of this work was to analyze a corpus of Chemistry abstracts, seeking the rhetoric categories that structure them in the sentence level and to describe its rubric. In order to do that, we have used lexical and grammatical evidence to categorise the rhetoric role each sentence has. We have found that the expected structure occurs, the main rhetoric focus being the presentation of results in the vast majority of cases. Furthermore, the occurrence of certain categories may depend on the size of the abstract, and certain rhetoric roles are embedded in others, especially the one describing method. The corpus has yet to be expanded to offer further results, two of them being to help non-native writers to better structure the textual level of their works and to build a software of automatic analysis of abstracts
