Ionization of NO by superhalogens: DFT and QTAIM approaches

Nitric oxide (NO) is a precursor to NO2, toxic gas, and a major air pollutant. Its ionization has been difficult due to its high ionization energy. We propose here the ionization of NO to NO+ using superhalogens. We study the interaction of NO with superhalogens (X = LiF2, BeF3 and, BF4) using DFT and QTAIM approaches, which lead to the formation of NO-X complexes. These complexes and their isomers are ionic with positively charged NO, which can be stabilized by two F–N bonds and F–O bonds, respectively. This reveals that NO can be ionized by electron transfer to superhalogens. The size of superhalogens has been noticed to play a crucial in the ionization of NO.

The Relationship

Cruchet et al. attempt to tease out the myths and facts surrounding the growing popularity of certain dietary approaches in the management of neurodevelopmental disorders, like attention-deficit hyperactivity disorder (ADHD) and autism spectrum disorders (ASDs). The authors identify a particular exclusionary-type approach that seeks to eliminate dietary gluten. Although the relationship between celiac disease (CD) and ADHD/ASD is not well established, a repeated clinical feature noted in CD is the elevated levels of nitric oxide in serum and urine. Elevated oxidative stress has also been observed in neurodevelopmental conditions, and the author of this correspondence has been the first to propose that chronic, environmental exposure to the air pollutant, nitrous oxide may contribute to these oxidative stress profiles through neural cholinergic perturbation. Therefore, the purpose of this correspondence is to highlight this biochemical connection between these conditions so as to identify the clinical populations who may realize the greatest benefit of these dietary approaches, while minimizing any potential risk of nutrient deficiencies.
