The radical chemistry has become an inevitable tool to the organic chemists now a days for the formation of carbon-carbon bonds. Prolific use of this particular field of chemistry is well established and growing continuously for the synthesis of carbocyclic as well as heterocyclic natural products. High stereo-and regioselectivity and mildness of the radical technique unaffecting various sensit...

Organic salts, such as Fe, Ca, and Mg oxalates acetates, may be widespread radiolysis oxidation products of organic matter in Martian surface sediments. Such salts are challenging to identify by evolved gas analysis but the ubiquitous CO2 CO pyrolysis data from Sample Analysis at Mars (SAM) instrument suite on Curiosity rover indirectly points their presence. Here, we examined laboratory result...

In the context of climate change, water management is crucial for controlling reproductive growth and quality grapes. this study, we aim to determine effects different regimes on yield components chemical composition grape Vitis vinifera Albariño grown in Galicia. Four treatments were tested trial: rainfed (T0), irrigated at 30% ETo from veraison harvest (T1), pea-size (T2), throughout whole ve...

We present here a detailed conformational analysis of menthyl acetate, one the constituents peppermint oil. Two conformers acetate were observed in broadband rotational spectrum 2–12 GHz frequency range. The structure lowest energy conformer was obtained from experiment based on assignment singly-substituted 13C-isotopologues. Additionally, internal dynamics methyl top acetyl side group charact...
