Comment on "Orientational Distribution of Free O-H Groups of Interfacial Water is Exponential"

In a recent letter (PRL,121,246101,2018), Sun et al. reported that combined MD simulation and sum frequency generation vibrational spectroscopy (SFG-VS) measurements led to conclusions of a broad and exponentially decaying orientational distribution, and the presence of the free O-H group pointing down to the bulk at the air/water interface. In this comment, we show that their main conclusions are based on questionable interpretation of the SFG-VS data presented in the letter [1], and are also contrary to the established data analysis and interpretations in the literature [2-5].Comment: 2 pages, 0 figure

Impact of COVID-19 on Cross-cultural Learning from Malaysia-to-Japan Research Exchange

Outbound research exchange program to Japanese Higher Education Institutes is very popular among Malaysian researchers. During the exchange program, bilateral cultural learning occurs between researchers from Malaysia and Japan. Mutual cultural understanding accelerates the respect for foreign cultures and enables cultural diversity to flourish in the globalized world. However, the COVID-19 outbreak has shattered the traditional cultural learning paradigm. This study analyzes the cultural components of the Japanese exchange program disrupted by the pandemic. A survey with a Likert scale of 1 to 5 was conducted to investigate the disruption of continuous cultural learning in terms of lifestyle, language, social value, and trends experienced by Malaysian researchers after the pandemic. The results show that the Japanese social values are influencing Malaysian researchers and the disruption caused by the pandemic is significant

Orientation and Motion of Water Molecules at Air/Water Interface

Analysis of SFG vibrational spectra of OH stretching bands in four experimental configurations shows that orientational motion of water molecule at air/water interface is libratory within a limited angular range. This picture is significantly different from the previous conclusion that the interfacial water molecule orientation varies over a broad range within the vibrational relaxation time, the only direct experimental evidence for ultrafast and broad orientational motion of a liquid interface by Wei et al. [Phys. Rev. Lett. 86, 4799, (2001)] using single SFG experimental configuration
